po: update translations and regenerate POT file and PO files

When there is no end match after a start, it is pointless to look
for any more starts because also they will not have any end match,
so nothing will get painted -- just cut the loop short.

-GNU nano upgrading information
-==============================
+Improvements in GNU nano
+========================
+
+Since 2.7.0:
+  - The keystroke ^] to complete a fragment to an existing full word.
+  - The ability to display line numbers in front of the text (M-#).
+
+Since 2.6.0:
+  - Shift plus the cursor keys can be used for selecting text.
+  - Ctrl+Arrow should now work also on a Linux virtual console.
+  - Ctrl+Up and Ctrl+Down jump to previous or next block of text.
+  - Feedback during Unicode Input (M-V followed by six digits).
+  - The option 'wordchars' for specifying extra word characters.
+  - Hi-bit control characters are shown in a more readable manner.
+  - The ability to use negative numbers at the Go To Line prompt.
+
+Noteworthy changes since 2.2
+----------------------------
+  - The ability to comment/uncomment lines with a single keystroke (M-3).
+  - The ability to refresh the file list in the browser (^L).
+  - The ability to abort re-searches (^C after an M-W).
+  - Better feedback at startup when opening large or multiple files.
+  - The option 'justifytrim' for snipping whitespace from justified lines.
+  - The ability to discard a buffer (^O ^Q) when --tempfile is used.
+  - Replacing things in a marked region now takes place in situ, in context,
+    instead of changing the view to only the marked text.
+  - On some terminals Ctrl+Left / Ctrl+Right now work for PrevWord/NextWord.
+  - When in the middle of a word, PrevWord now jumps to the start of this
+    word (like Pico does) instead of to the start of the preceding word.
+  - Invalid byte sequences are properly displayed and not mistakenly found.
+  - Resizing the window does not exit from help viewer nor file browser.
+  - Improved arrangement of the shortcuts in the two help lines.
+  - Several small bug fixes in the syntax highlighting.
+  - System syntaxes can be improved upon with the 'extendsyntax' command.
+  - The ability to delete whole words with 'cutwordleft' and 'cutwordright'.
+  - The ability to save a file without prompting for its name ('savefile').
+  - The ability to search backward without having to toggle the direction.
+  - Whitespace display (M-P) does not require configuration to be useful.
+  - Undo/redo is enabled by default (M-U/M-E) and works nearly everywhere
+    -- just not yet for justifying and indenting/unindenting.
+  - The ability to color the title bar, the status bar and the help lines.
+  - The ability to run a linter or formatter (^T) on the current buffer.
+  - The ability to only write to named pipes with --noread.
+  - Determination of the applicable syntax through libmagic -- when the
+    file extension nor the first line give an answer.
+  - The option 'positionlog' for saving/restoring the cursor position.
+  - The ability to read and write vim-style lock files.

+2017.01.10 - GNU nano 2.7.4 "Red dress" undoes deletions in an orderly
+		manner again (bug was introduced in previous version),
+		sets the preferred x position for vertical movements
+		more consistently, avoids some scrolling problems in
+		softwrap mode, installs the Info manual also when your
+		system lacks 'makeinfo', and corrects the behavior of
+		the beginning-of-word anchor (\<) in regex searches.
+
+2016.12.28 - GNU nano 2.7.3 "Ontbijtkoek" wipes away a handful of bugs:
+		your editor is now able to handle filenames that contain
+		newlines, avoids a brief flash of color when switching
+		between buffers that are governed by different syntaxes,
+		makes the Shift+Ctrl+Arrow keys select text again on a
+		Linux console, is more resistant against malformations
+		in the positionlog file, and does not crash when ^C is
+		typed on systems where it produces the code KEY_CANCEL.
+		Oh, and it no longer mistakenly warns about editing an
+		unlocked file just after saving a new one.  That's it.
+		Tastes great with thick butter.
+
+2016.12.12 - GNU nano 2.7.2 "Shemesh! Shemesh!" brings another feature:
+		the ability to complete with one keystroke (^] by default)
+		a fragment of a word to a full word existing elsewhere in
+		the current buffer.  Besides, this release fixes two bugs
+		related to using line numbers in softwrap mode, allows to
+		use the PageUp and PageDown keys together with Shift on
+		VTE-based terminals, stops the help lines from flickering
+		during interactive replacing, makes a "set fill" override
+		an earlier "set nowrap", properly restores the selected
+		region after an external spell check, and improves a few
+		other tidbits.  If you should find any more bugs, please
+		run 'man nano | grep bugs' and report them there.
+
+2016.10.29 - GNU nano 2.7.1 "Leuven" adds an often-asked-for feature: the
+		ability to display line numbers beside the text.  This can
+		be activated with -l or --linenumbers on the command line,
+		or with 'set linenumbers' in your nanorc, or toggled with
+		M-#.  The coloring of these numbers can be chosen via the
+		option 'set numbercolor'.  This release furthermore fixes
+		some bugs with scrolling in softwrap mode, is more strict
+		in the parsing of key rebindings, and marks a new buffer
+		as modified when the output of a command (^R ^X) has been
+		read into it.  Come and check it out!
+
+2016.09.01 - GNU nano 2.7.0 "Suni" adds a new feature: allowing text to be
+		selected by holding Shift together with the cursor keys.
+		Besides that, nano now works also when run in very tiny
+		terminals (down to one line, one column), and improves
+		the handling of the prompt in cramped spaces.  Not much,
+		but it's time to get it out there.
+
+
+2016.08.10 - nano 2.6.3 "Marika" makes the Ctrl+Arrow keys work also on
+		a Linux virtual console, takes as verbatim only the very
+		first keystroke after M-V, removes any lock files that it
+		holds when dying, doesn't abort when a word contains digits
+		(when using the default speller), fixes a small sorting bug
+		in the file browser, makes searching case-insensitively in
+		a UTF-8 locale a little faster, and doesn't enter invalid
+		bytes when holding down both Alt keys.  Santé!
+
+2016.07.28 - nano 2.6.2 "Le vent nous portera" adds two new features: the
+		keystrokes Ctrl+Up and Ctrl+Down for jumping between blocks
+		of text, and the option 'wordchars' for specifying which
+		characters (beside alphanumeric ones) should be considered
+		word-forming.  Further, it provides feedback during Unicode
+		input (M-V followed by a six-digit hexadecimal number which
+		must start with 0 or 10), avoids a crash when resizing the
+		window during Verbatim input, doesn't drop a keystroke after
+		having been suspended, and replaces the	beginning-of-line
+		anchor (^) just once per line.  There are also several tiny
+		improvements in screen rendering and key handling.  Come get
+		your hair tousled!
+
+2016.06.27 - nano 2.6.1 "Stampede" is chiefly a translation update, but also
+		adds one little feature (the ability to use negative numbers
+		with Go To Line: -1 meaning the first line from the bottom),
+		includes syntax highlighting for Rust, and fixes three tiny
+		bugs (but in such far corners of the editor that they aren't
+		even worth mentioning).
+
+2016.06.17 - nano 2.6.0 "Rubicon" fixes more than fifty little bugs -- and
+		some of them not so little.  It improves moving about in
+		the file browser, corrects failings of the internal spell
+		checker, adds a new feature (comment/uncomment lines, with
+		default binding M-3), makes some error messages clearer,
+		shows more of a file when positionlog is used and the cursor
+		is near the end, displays all error messages at startup if
+		there are multiple ones, does not misinterpret keystrokes
+		when typing very fast, is less eager to trim the filename
+		on narrow terminals, speeds up case-insensitive searches,
+		and allows to abort re-searches.  Among bunches of other
+		things.  It is worth the trouble to upgrade.
+
+
+2016.02.25 - GNU nano 2.5.3 "Alphys" is released.  This release
+		contains fixes for bugs like: stray cursor positioning
+		errors, many many memory leaks including file reading,
+		using the file browser, searching for multibyte characters,
+		history completion, and many other places.
+			New features include the ability to trim whitespace
+		from the ends of lines when justifying text, see nanorc(5)
+		option justifytrim for deets.  As always thank you for your
+		continued support of nano, and keep sparing.
+
+2016.02.12 - GNU nano 2.5.2 is carrying too many dogs.  This release includes
+		several fixes for various memory leaks, position history
+		size growth, and a long standing issue with using
+		nano under sudo creating root-owned files.  There are also
+		the usual bevy of documentation and other miscellaneous
+		fixes and touchups.  Upgrade today while supplies last,
+		operators are standing by!
+
+2016.01.11 - GNU nano 2.5.1 "Salzburg" is released.  It includes fixes
+		for a syntax-highlighting bug and a positionlog bug, it
+		disables a time-eating multiline regex in the C syntax,
+		and it adds an escape hatch to the WriteOut menu when
+		--tempfile is used: the discardbuffer command, ^Q.  It
+		also has translation updates for fifteen languages, and
+		a small fix in the softwrap code.  So... you are heartily
+		invited to upgrade.  Enjoy!
+
+2015.12.05 - GNU nano 2.5.0 "Karma", the first release of the 2.5 series,
+		is now available.  Please note that as of this release,
+		there will no longer be separate stable and unstable
+		branches.  The development team will prioritize bug fixes
+		as needed, and make new releases in proportion to the
+		severity of the bugs which are fixed.
+			This release includes all of the fixes now in
+		2.4.3, as well as color syntax highlighting improvements,
+		undo fixes, and many more improvements!  Thank you for
+		using nano!
+
+
+2015.11.18 - GNU nano 2.4.3 "Apocalypse" is now available for your
+		downloading pleasure.  This release includes a myriad
+		of fixes including several memory leaks, issues with
+		color syntax highlighting, search/replace, file
+		insertion and help menu bugs.  Many thanks to
+		Benno Schulenberg for tireless efforts on the vast
+		majority of fixes for some time now.  As always please
+		report bugs via the Savannah page, and remember to

+
+2015.07.05 - GNU nano 2.4.2 "Portorož" is released.  This release

+INSTRUCTIONS FOR COMPILING AND INSTALLING NANO FROM GIT
+=======================================================
+
+The latest changes and fixes for GNU nano are available via git, but
+building this needs a bit more care than the official tarballs.
+
+
+Prerequisites
+-------------
+
+To successfully compile GNU nano from git, you'll need the following
+packages:
+
+- autoconf    (version >= 2.61)
+- automake    (version >= 1.7)
+- autopoint   (version >= 0.11.5)
+- gettext     (version >= 0.11.5)
+- git         (version >= 2.7.4)
+- groff       (version >= 1.12)
+- pkg-config  (version >= 0.22)
+- texinfo     (version >= 4.0)
+- gcc         (any version)
+- make        (any version)
+
+If you want UTF-8 support, you will also need libncursesw5-dev installed
+(version >= 5.7), or libslang2-dev (version >= 2.0) if you use --with-slang.
+If your system doesn't have 'snprintf' or 'vsnprintf' (which the configure
+script will check for), you will also need glib-2.x installed.
+
+These should all be available in your distro's package manager or software
+center, or otherwise on any GNU mirror.
+
+
+Download the source
+-------------------
+
+To obtain the current nano development branch (called 'master'), use the
+following command.  It will create in your current working directory a
+subdirectory called 'nano' containing a copy of all of the files:
+
+    $ git clone git://git.savannah.gnu.org/nano.git nano
+
+
+Generate the configure script
+-----------------------------
+
+Once you have the sources in the "nano" directory,
+
+    $ cd nano
+    $ ./autogen.sh
+
+This will set up a configure script and a Makefile.in file.
+
+
+Configure your build
+--------------------
+
+To configure your build, run the configure script from the nano source
+directory:
+
+    $ ./configure [--add-options-here]
+
+
+Build and install
+-----------------
+
+From the nano source directory, build the code with:
+
+    $ make
+
+Then, once it's done compiling, run:
+
+    $ make install
+
+which should copy various files (i.e. the nano executable, the info and
+man pages, and syntax highlighting pattern files) to their appropriate
+directories.
+
+If you're installing into the default install directory (/usr/local),
+you'll need to run that "make install" command with root privileges.
+
+
+Problems?
+---------
+
+Please submit any bugs you find in the code in git via the bug tracker
+on Savannah (https://savannah.gnu.org/bugs/?group=nano).
+
+
+Contributing something
+----------------------
+
+If you have a fix for a bug, or the code for a new or improved feature,
+first create a branch off of master:
+
+    $ git checkout -b somename
+
+Then change the code so it does what you want, and commit it, with in the
+commit message (after the one-line summary) a rationale for the change:
+
+    $ git commit -as
+
+Then create a patch (or patches):
+
+    $ git format-patch master
+
+Send that patch (or patches) to <nano-devel@gnu.org>, as an attachment
+or with git send-email.

-INSTRUCTIONS TO COMPILE AND INSTALL NANO CVS VERSIONS
-=====================================================
-
-GNU nano is available from SVN, but building this needs a bit more care
-than the official stable and unstable tarballs.
-
-
-Prerequisites
--------------
-
-To successfully compile GNU nano from CVS, you'll need the following
-packages:
-
-- autoconf (version >= 2.54)
-- automake (version >= 1.7)
-- gettext  (version >= 0.11.5)
-- groff    (version >= 1.12)
-- texinfo  (version >= 4.0)
-- subversion (aka svn)
-- glib 2.x (if your system doesn't have vsnprintf(), which the configure
-  script will check for)
-- make, gcc and the normal development libraries (curses or slang, etc.)
-
-These should be available on your GNU mirror.  Note that you'll need a
-version of curses or slang with wide character support if you want nano
-to use UTF-8.
-
-
-Download the source
--------------------
-
-To obtain the current nano development code (called 'trunk'), use the
-following command.  It will create a copy of the files in a subdirectory
-of your current working directory called 'nano':
-
-    $ svn co svn://svn.savannah.gnu.org/nano/trunk/nano
-
-If you want to download the stable SVN branch instead, use:
-
-    $ svn co svn://svn.savannah.gnu.org/nano/branches/nano_2_2_branch/nano
-
-
-Generate the configure script
------------------------------
-
-Once you have the sources in the "nano" directory,
-
-    $ cd nano
-    $ ./autogen.sh
-
-This will set up a configure script and a Makefile.in file.
-
-
-Configure your build
---------------------
-
-To configure your build, run the configure script from the nano source
-directory:
-
-    $ ./configure [--add-options-here]
-
-
-Build and install
------------------
-
-From the nano source directory, build the code with:
-
-    $ make
-
-Then, once it's done compiling, run
-
-    $ make install
-
-which should copy various files (i.e. the nano executable, the info and
-man pages, and syntax highlighting pattern files) to their appropriate
-directories.
-
-If you're installing into the default install directory (/usr/local),
-you'll need to run that "make install" command with root privileges.
-
-
-Problems?
----------
-
-Please submit any bugs in the SVN branch using the Savannah project's
-bug tracker (https://savannah.gnu.org/bugs/?group=nano).

   <p>The <a href="http://www.debian.org/">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly &quot;free&quot; software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but the versions available at the time were not truly free software in the <a href="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>
   <p><b>The event...</b></p>
   <p>It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.</p>
-  <p>Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help text display, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is today.</p>

   <p>In February 2001, nano was declared an official GNU program by Richard Stallman. nano also reached its first production release on March 22, 2001.</p></blockquote>
 <h2><a name="1.5"></a>1.5. Why the name change from TIP?</h2>
 <blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program &quot;establishes a full duplex terminal connection to a remote host&quot;, and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>

-<blockquote><p>To use multiple file buffers, you must be using nano 1.1.0 or newer, and you must not have configured it with <b>--disable-multibuffer</b> nor with <b>--enable-tiny</b> (use <b>nano -V</b> to check the compilation options).

-<h2><a name="3.9"></a>3.9. How do I make a .nanorc file that nano will read when I start it?</h2>

Then simply copy the <b>nanorc.sample</b> that came with the nano source or your nano package (most likely in /usr/doc/nano) to .nanorc in your home directory.

In Windows XP, you can get to Environment variables by right-clicking "My Computer" either on the desktop or in the Start Menu, and selecting Properties.  This should bring up the System Properties panel.  Then click the Advanced Tab, and there should be a button called Environment Variables.  Click that to bring up the Environment Variables section. Now, under User Variables you should be able to click the New button, and make a new Variables Name called HOME, with the Variable Value of whatever path you copied nano.rc into (just the directory name; don't add nano.rc onto the end).</p>

-<blockquote><p>It was decided that consistency was nice, but people are used to Pico's inconsistent behavior. Also, in version 1.1.99pre1, search and replace history was introduced. If you wish to edit your previous search/replace entry (or any previous entry), you can do so by hitting the up arrow to cycle through your history. This method allows the best of both worlds: You don't need to erase the previous string if you want to enter a new one, but you can with one keystroke recall previous entries for editing. Therefore there is now no "Pico mode", nano is and has always been a Pico <b>clone</b>, and clones by default should be compatible.</p></blockquote>

-2006/07/25 - Update section 5.3 again to not state &quot;the latest development version&quot; before 1.3.12, as it's no longer accurate. Also add some minor spacing fixes. (DLR)<br>

+<blockquote><p>The easiest way is to consistently send in good patches that add some needed functionality, fix a bug or two, and/or make the program more optimized/efficient. Then ask nicely and you will probably be added to the Savannah development list and be given write access after a while. There is a lot of responsibility that goes along with being a team member, so don't think it's just something to add to your resume.</p></blockquote>

-.SH NOM
-nano \- NAno un NOuvel éditeur, un clone libre et amélioré de Pico
-
-.SH SYNOPSIS
-.B nano
-.I [OPTIONS]\ [[+LIGNE,COLONNE]\ FICHIER]...
-.br
-
-.SH DESCRIPTION
-Cette page de manuel décrit brièvement la commande \fBnano\fR.
-.PP
-.\" TeX users may be more comfortable with the \fB<whatever>\fP and
-.\" \fI<whatever>\fP escape sequences to invoke bold face and italics,
-.\" respectively.
-\fBnano\fR est un éditeur petit, sympathique et libre, qui vise à remplacer
-Pico, l'éditeur par défaut du logiciel non libre Pine. \fBnano\fR ne se
-contentant pas de copier l'interface et l'ergonomie de Pico, il offre
-également certaines fonctions manquantes (ou désactivées par défaut)
-dans Pico. Ces fonctionnalités sont, par exemple, les fonctions de
-recherche et de remplacement, et la possibilité de sauter directement à 
-une ligne et à une colonne précise.
-
-.SH OPTIONS
-.TP
-.B +\fILIGNE\fP,\fICOLONNE\fP
-Démarre avec le curseur positionné à la colonne \fICOLONNE\fP de 
-la ligne \fILIGNE\fR (l'un des deux, au moins, devant être spécifié) au 
-lieu de démarrer à la colonne\ 1, ligne\ 1.
-.TP
-.B \-?
-Identique à \fB\-h (\-\-help)\fP.
-.TP
-.B \-A (\-\-smarthome)
-Rend plus malin le fonctionnement de la touche «\ Début\ ». Lorsque l'on
-appuie sur cette touche à n'importe quel endroit excepté au tout début
-du texte d'une ligne (i.\ e. au premier caractère non blanc), le curseur
-se positionnera au début du texte de la ligne (qu'il soit en avant ou en
-arrière). Si le curseur est déjà là, il se placera au vrai début de la
-ligne.
-.TP
-.B \-B (\-\-backup)
-Lors de l'écriture d'un fichier, crée une copie de sécurité de la
-version précédente, en ajoutant un tilde (~) au nom du fichier.
-.TP
-.B \-D (\-\-boldtext)
-Utilise des caractères gras à la place de la vidéo inverse.
-.TP
-.B \-C \fIrépertoire\fP (\-\-backupdir=\fIrépertoire\fP)
-Définit le répertoire utilisé par \fBnano\fP pour enregistrer les copies 
-de sécurité uniques si celles-ci sont activées.
-.TP
-.B \-E (\-\-tabstospaces)
-Convertit les tabulations clavier en espaces.
-.TP
-.B \-F (\-\-multibuffer)
-Active le mode multi-espace, autorisant l'édition simultanée de 
-plusieurs fichiers, si ce mode est disponible.
-.TP
-.B \-H (\-\-historylog)
-Enregistre les chaînes ayant fait l'objet d'une recherche ou d'un
-remplacement dans le fichier \fI~/.nano_history\fR afin de permettre leur
-réutilisation. Ceci n'est possible que si \fBnano\fR est configuré pour
-utiliser les fichiers nanorc.
-.TP
-.B \-I (\-\-ignorercfiles)
-Ne pas utiliser pas les fichiers \fISYSCONFDIR/nanorc\fR et 
-\fI~/.nanorc\fR (si \fBnano\fR est capable de les utiliser).
-.TP
-.B \-K (\-\-rebindkeypad)
-Interprète les touches du pavé numérique afin qu'elles fonctionnent 
-toutes correctement. Vous ne devriez utiliser cette option que si ce 
-n'est pas le cas, car nano ne sera plus capable d'utiliser la souris 
-correctement lorsque cette option sera activée.
-.TP
-.B \-L (\-\-nonewlines)
-Ne pas ajouter de passage à la ligne à la fin des fichiers.
-.TP
-.B \-N (\-\-noconvert)
-Désactive la conversion automatique des fichiers depuis les formats Mac et
-DOS.
-.TP
-.B \-O (\-\-morespace)
-Utiliser la ligne blanche située sous la ligne de titre comme
-espace supplémentaire d'édition.
-.TP
-.B \-Q \fIchaîne\fP (\-\-quotestr=\fIchaîne\fP)
-Définit le préfixe par défaut des citations. Nano utilise ce préfixe
-pour réaliser une justification correcte des citations. Si nano est
-capable d'utiliser des expressions rationnelles, le préfixe par défaut
-sera "\fI^([\ \\t]*[#:>\\|}])+\fP", sinon, ce sera "\fI>\ \fP". Dans 
-l'expression rationnelle précédente, «\ \fI\\t\fP\ » représente une 
-tabulation.
-.TP
-.B \-R (\-\-restricted)
-Mode restreint\ : aucune lecture ou écriture de fichiers non indiqués 
-sur la ligne de commande, pas de lecture des fichiers nanorc, 
-interdiction de suspendre, interdiction d'ajouter au début, à la fin, 
-de sauvegarder un fichier ayant déjà un nom sous un nom différent, 
-d'utiliser une copie de sécurité ou le correcteur orthographique. Cette 
-option peut aussi être activée en appelant \fBnano\fP sous un nom 
-commençant par «\ r\ » (par exemple «\ rnano\ »).
-.TP
-.B \-S (\-\-smooth)
-Active le défilement progressif. Le texte défilera ligne-par-ligne au lieu
-de défiler morceau-par-morceau.
-.TP
-.B \-T \fInombre\fP (\-\-tabsize=\fInombre\fP)
-Définit la taille (largeur) des tabulations en nombre de colonnes. Le 
-nombre indiqué doit être strictement supérieur à 0. La valeur par défaut 
-est de 8.
-.TP
-.B \-U (\-\-quickblank)
-Effacement rapide de la ligne d'état. Les messages affichés par la ligne 
-d'état disparaîtront après une frappe clavier au lieu de 25. Notez que
-l'option \fB-c\fP prend le pas sur cette option.
-.TP
-.B \-V (\-\-version)
-Affiche la version, puis s'arrête.
-.TP
-.B \-W (\-\-wordbounds)
-Détection plus précise des limites de mots, obtenue en considérant les 
-caractères de ponctuation comme faisant partie des mots.
-.TP
-.B \-Y \fIchaîne\fP (\-\-syntax=\fIchaîne\fP)
-Indique quel mode de colorisation syntaxique adopter, parmi les modes
-définis dans le fichier \fI.nanorc\fR, si cette fonctionnalité est
-disponible.
-.TP
-.B \-c (\-\-const)
-Affiche en permanence la position du curseur. Notez que cette option

-.SH "FICHIERS D'INITIALISATION"
-\fBnano\fR lit les fichiers d'initialisation dans l'ordre suivant\ : 
-\fISYSCONFDIR/nanorc\fR, puis \fI~/.nanorc\fR. Référez-vous à la page de 
-manuel de \fBnanorc(5)\fR et au fichier d'exemple \fInanorc.sample\fR, 
-qui devraient tous les deux être livrés avec \fBnano\fR.
-
-.SH NOTES
-Si aucun correcteur orthographique de remplacement n'est indiqué dans la 
-ligne de commande ou dans l'un des fichiers nanorc, \fBnano\fR prendra 
-la commande indiquée par la variable d'environnement \fBSPELL\fR si 
-elle est définie.
-
-Dans certains cas, \fBnano\fR essaiera de sauvegarder le fichier en cours
-d'édition dans un fichier de secours. Cela arrivera principalement si
-\fBnano\fR reçoit un signal SIGHUP ou SIGTERM, ou bien se trouve à court de
-mémoire. Le nom de ce fichier de secours sera \fInano.save\fR si le fichier en
-cours n'avait pas encore de nom, ou sera composé du nom du fichier en cours
-suivi du suffixe «\ .save\ ». Si un fichier de ce nom existe déjà dans
-le répertoire, un «\ .save\ » et un nombre seront ajoutés à la fin du
-nom du fichier en cours afin de le rendre unique (par exemple,
-«\ .save.1\ »). En mode multi-espace, \fBnano\fR réalisera une
-sauvegarde de tous les fichiers en cours dans leurs fichiers de secours
-respectifs.

-.SH NOM
-nanorc \- fichier de configuration de l'éditeur nano du projet GNU 
-
-.SH DESCRIPTION
-Cette page de manuel décrit brièvement le fichier de configuration de 
-l'éditeur \fBnano\fP GNU.
-.PP
-\fBnano\fP est un petit éditeur sympathique et libre, qui vise à 
-remplacer Pico, l'éditeur par défaut du logiciel non libre Pine. 
-\fBnano\fP ne se contentant pas de copier l'interface et l'ergonomie de 
-Pico, il offre également certaines fonctionnalités manquantes (ou 
-désactivées par défaut) de Pico. Ces fonctionnalités sont, par exemple, 
-les fonctions de recherche et de remplacement et la possibilité de 
-sauter directement à une ligne et à une colonne précise.
-.PP
-Le fichier \fInanorc\fP contient les paramètres par défaut de 
-\fBnano\fP. Il ne doit pas être au format DOS ou Mac. Lors de son 
-démarrage, nano commencera par lire le fichier de configuration général 
-\fISYSCONFDIR/nanorc\fP, puis lira le fichier de configuration personnel 
-de l'utilisateur \fI~/.nanorc\fP.
-
-.SH OPTIONS
-Le fichier de configuration accepte une série de commandes \fBset\fP 
-(activer) et \fBunset\fP (désactiver), qui permettent de définir le 
-paramétrage de nano au démarrage sans avoir à utiliser d'options de
-ligne de commande. De plus, les mots clefs \fBsyntax\fP (syntaxe),
-\fBcolor\fP (couleur) et \fBicolor\fP (couleur insensible à la casse) 
-sont utilisés pour définir les règles de colorisation pour différents 
-motifs de texte. \fBnano\fP lit une commande par ligne.
-
-Les options du fichier de configuration ont priorité sur les valeurs par 
-défaut utilisées par nano. Les options de la ligne de commande sont 
-prioritaires par rapport aux options du fichier de configuration. Les 
-options sont désactivées (unset) par défaut, sauf les options prenant un 
-argument.
-
-Les apostrophes («\ \fI'\fP\ ») et les guillemets droits («\ \fI"\fP\ »)
-présents dans des chaînes de caractères utilisées comme paramètres n'ont 
-pas besoin d'être précédées d'une barre oblique inversée
-(«\ \fI\\\fP\ »). La chaîne sera terminée par le dernier guillemet 
-droit. Par exemple, pour l'option \fBbrackets\fP, "\fI"')>]}\fP" 
-correspondra à \fI"\fP, \fI'\fP, \fI)\fP, \fI>\fP, \fI]\fP et \fI}\fP.
-
-Les commandes et arguments reconnus sont\ :
-
-.TP 3
-.B set/unset autoindent
-Active l'indentation automatique.
-.TP
-.B set/unset backup
-Crée des copies de sécurité nommées
-.IR nom_du_fichier~ .
-.TP
-.B set backupdir "\fIrépertoire\fP"
-Définit le répertoire utilisé par \fBnano\fP pour enregistrer les copies 
-de sécurité uniques, si l'enregistrement de copies de sécurité est 
-activé.
-.TP
-.B set/unset backwards
-Par défaut, les recherches se font vers l'arrière.
-.TP
-.B set/unset boldtext
-Utilise des caractères gras à la place de la vidéo inverse.
-.TP
-.B set brackets "\fIchaîne\fP"
-Définit les caractères considérés comme des crochets fermants lors de la 
-justification des paragraphes. Ces caractères ne doivent pas contenir 
-d'espaces. Seules les ponctuations terminales, éventuellement suivies 
-de crochets fermants, peuvent terminer une phrase.
-
-La valeur par défaut de cette option est\ : "\fI"')>]}\fP".
-
-N.D.T.\ : reportez-vous au paragraphe sur l'option \fBpunct\fR pour 
-plus d'informations.
-
-.TP
-.B set/unset casesensitive
-Par défaut, les recherches ne tiennent pas compte de la casse.
-.TP
-.B set/unset const
-Affiche en permanence la position du curseur dans la ligne d'état.
-.TP
-.B set/unset cut
-Par défaut, coupe le texte du curseur à la fin de la ligne, au lieu de 
-couper la ligne entière.
-.TP
-.B set fill \fIn\fP
-Passe automatiquement à la ligne une fois arrivé à la colonne 
-\fIn\fR. Si la valeur indiquée est de 0 ou moins, le point de passage à 
-la ligne aura lieu à la taille de l'écran moins \fIn\fR. Cela permet de 
-faire varier le point de passage à la ligne lorsque l'on change la 
-taille de l'écran. La valeur par défaut est de \-8.
-.TP
-.B set/unset historylog
-Active l'utilisation de
-.I ~/.nano_history
-pour enregistrer et relire les chaînes ayant fait l'objet d'une 
-recherche ou d'un remplacement.
-.TP
-.B set matchbrackets "\fIchaîne\fP"
-Définit les crochets ouvrants et fermant pour la recherche de crochets 
-correspondants. Cette liste ne doit pas contenir de blancs. L'ensemble 
-des crochets ouvrants doit être indiqué en premier, suivi de l'ensemble 
-des crochets fermant, qui doit être dans le même ordre. La valeur par 
-défaut de cette option est "\fI(<[{)>]}\fP".
-.TP
-.B set/unset morespace
-Utiliser la ligne blanche située sous la ligne de titre comme espace 
-supplémentaire d'édition.
-.TP
-.B set/unset mouse
-Active l'utilisation de la souris, si elle est disponible pour votre
-système. Lorsque celle-ci est activée, il est possible d'utiliser la
-souris pour positionner le curseur, pour marquer le texte (avec un
-double-clic) et pour lancer les fonctions correspondant aux raccourcis.
-Il est possible d'utiliser la souris sous X\ Window ou en mode console
-avec gpm.
-.TP
-.B set/unset multibuffer
-Mode multi-espace\ : permet de charger les fichiers dans leur propre 
-espace.
-.TP
-.B set/unset noconvert
-Pas de conversion depuis les formats DOS et Mac.
-.TP
-.B set/unset nofollow
-Ne suit pas les liens symboliques lors de l'écriture des fichiers.
-.TP
-.B set/unset nohelp
-Désactive les lignes d'aide affichée en bas de l'écran.
-.TP
-.B set/unset nonewlines
-Ne pas ajouter de passage à la ligne à la fin des fichiers.
-.TP
-.B set/unset nowrap
-Désactive le passage automatique à la ligne.
-.TP
-.B set operatingdir "\fIrépertoire\fP"
-\fBnano\fP ne lira et n'écrira des fichiers qu'à l'intérieur du 
-\fIrépertoire\fP et de ses sous-répertoires. De plus, celui-ci devient 
-le répertoire courant, afin que les fichiers soient lus depuis ce 
-répertoire. Par défaut, cette fonction est désactivée.
-.TP
-.B set/unset preserve
-Préserve les séquences XON et XOFF (^Q et ^S).
-.TP
-.B set punct "\fIchaîne\fP"
-Définit les caractères interprétés comme des ponctuations terminales 
-lors de la justification des paragraphes. Ces caractères ne peuvent 
-inclure de blancs. Seules les ponctuations terminales, éventuellement 
-suivies de crochets fermants, peuvent terminer une phrase. La valeur par 
-défaut de cette option est "\fI!.?\fP".
-
-N.D.T.\ : ce réglage permet, lors de la justification, de conserver
-2\ espaces au lieu d'une derrière les ponctuations terminales, ce qui 
-correspond aux normes typographiques anglo-saxonnes, mais n'a pas lieu 
-d'être en français. Pour le français, le plus simple est d'indiquer, 
-dans le fichier nanorc, une chaîne vide pour ce paramètre.
-.TP
-.B set/unset quickblank
-Effacement rapide de la ligne d'état. Les messages affichés par la ligne
-d'état disparaîtront après une frappe clavier au lieu de 25.
-.TP
-.B set quotestr "\fIchaîne\fP"
-Définit le préfixe par défaut utilisé pour les citations dans les 
-courriers électroniques. Ce préfixe est utilisé pour réaliser une 
-justification correcte de ces citations. Il s'agira, si votre système le 
-permet, d'une expression rationnelle étendue. Dans le cas 
-contraire, il s'agira d'une chaîne de texte brut. Si vous disposez des 
-expressions rationnelles, la valeur par défaut de cette option sera 
-"\fI^([\ \\t]*[#:>\\|}])+\fP", sinon, ce sera ">\ ". Notez que le
-«\ \\t\ » ci-dessus correspond à un caractère de tabulation.
-.TP
-.B set/unset rebinddelete
-Interprète différemment la touche «\ Supprimer\ », afin que les touches 
-«\ Effacement arrière\ » et «\ Supprimer\ » fonctionnent correctement. 
-Vous ne devriez avoir besoin de cette option que si, sur votre système, 
-la touche «\ Effacement arrière\ » produit l'effet de la touche «\ 
-Supprimer\ ».
-.TP
-.B set/unset rebindkeypad
-Interprète les touches du pavé numérique afin qu'elles fonctionnent 
-toutes correctement. Vous ne devriez utiliser cette option que si ce 
-n'est pas le cas, car nano ne sera plus capable d'utiliser la souris 
-correctement lorsque cette option sera activée.
-.TP
-.B set/unset regexp
-Utilise par défaut des expressions rationnelles étendues pour les 
-recherches.
-.TP
-.B set/unset smarthome
-Rend plus malin le fonctionnement de la touche «\ Début\ ». Lorsque
-cette touche est pressée à n'importe quel endroit excepté au tout début
-du texte d'une ligne (i.\ e. au premier caractère non blanc), le curseur
-se positionnera au début du texte de la ligne (qu'il soit en avant ou en 
-arrière). Si le curseur est déjà là, il se placera au vrai début de la 
-ligne.
-.TP
-.B set/unset smooth
-Active le défilement ligne-par-ligne du texte.
-.TP
-.B set speller "\fIprogramme\fP"
-Utilise le correcteur orthographique \fIprogramme\fP au lieu du 
-correcteur intégré, qui s'appuie sur \fIspell\fP.
-.TP
-.B set/unset suspend
-Autorise à suspendre \fBnano\fP.
-.TP
-.B set tabsize \fIn\fP
-Utilise une taille de tabulation de \fIn\fP colonnes. Cette valeur doit 
-être strictement supérieure à 0. La valeur par défaut est de\ 8.
-.TP
-.B set/unset tabstospaces
-Convertit les tabulations clavier en espaces.
-.TP
-.B set/unset tempfile
-S'il a été modifié, le fichier sera sauvegardé automatiquement en 
-quittant, sans demande de confirmation.
-.TP
-.B set/unset view
-Interdit de modifier les fichiers.
-.TP
-.B set whitespace "\fIchaîne\fP"
-Définit les deux caractères utilisés pour afficher les premiers 
-caractères des tabulations et des espaces. Ces deux caractères doivent 
-être mono-colonne.
-.TP
-.B set/unset wordbounds
-Détection plus précise des limites de mots, obtenue en considérant les
-caractères de ponctuation comme faisant partie des mots.
-.TP
-.B syntax "\fIchaîne\fP" ["\fImotif_de_fichier\fP" ... ]
-Définit une syntaxe nommée \fIchaîne\fP qui pourra être activé via 
-l'option \fB-Y\fP (ou \fB--syntax\fP) ou qui sera automatiquement 
-activée si le nom du fichier en cours correspond à l'expression 
-rationnelle étendue \fImotif_de_fichier\fP. Toutes les instructions 
-suivantes de colorisation \fBcolor\fP ou \fBicolor\fP s'appliqueront à 
-cette syntaxe, jusqu'à la définition d'une nouvelle syntaxe.
-
-La syntaxe nommée \fInone\fP (aucune) est réservée\ ; si elle est 
-indiquée dans la ligne de commande, cela revient à ne définir aucune 
-syntaxe. La syntaxe nommée \fIdefault\fP (par défaut) est spéciale, elle 
-ne nécessite aucun motif de \fImotif_de_fichier\fP, et s'applique aux 
-fichiers ne correspondant à aucun des \fImotif_de_fichier\fP des autres 
-syntaxes.
-.TP
-.B color \fIcouleur_texte\fP[,\fIcouleur_fond\fP] "\fImotif\fP" ...
-Pour la syntaxe en cours, affiche toutes les expressions correspondant à 
-l'expression rationnelle étendue \fImotif\fP en utilisant la couleur de 
-texte \fIcouleur_texte\fP et la couleur de fond \fIcouleur_fond\fP, 
-l'une de ces deux couleurs au moins devant être définie. Les couleurs 
-acceptées par \fBnano\fP pour le texte et le fond sont\ : \fIwhite\fP 
-(blanc), \fIblack\fP (noir), \fIred\fP (rouge), \fIblue\fP (bleu), 
-\fIgreen\fP (vert), \fIyellow\fP (jaune), \fImagenta\fP, et \fIcyan\fP. 
-Pour la couleur du texte, vous pouvez ajouter à ces couleurs le préfixe 
-\fIbright\fP (lumineux) pour obtenir une couleur plus lumineuse. Si 
-votre terminal est capable de gérer la transparence, ne pas spécifier de 
-\fIcouleur_fond\fP indique à \fBnano\fP d'essayer d'utiliser un fond 
-transparent.
-.TP
-.B icolor \fIcouleur_texte\fP[,\fIcouleur_fond\fP] "\fImotif\fP" ...
-Comme ci-dessus, mais la recherche des motifs est effectuée sans tenir 
-compte de la casse.
-.TP
-.B color \fIcouleur_texte\fP[,\fIcouleur_fond\fP] start="\fImotif_début\fP" end="\fImotif_fin\fP"
-Affiche les expressions commençant par l'expression rationnelle étendue 
-\fImotif_début\fP et se terminant par l'expression rationnelle étendue 
-\fImotif_fin\fP en utilisant la couleur de texte \fIcouleur_texte\fP 
-et la couleur de fond \fIcouleur_fond\fP, l'une de ces deux couleurs au 
-moins devant être définie. Cela permet à la colorisation syntaxique de 
-s'étendre sur plusieurs lignes. Notez que toutes les occurrences 
-successives de \fImotif_début\fP après le \fImotif_début\fP initial 
-seront surlignées jusqu'à la prochaine instance de \fImotif_fin\fP.
-.TP
-.B icolor \fIcouleur_texte\fP[,\fIcouleur_fond\fP] start="\fImotif_début\fP" end="\fImotif_fin\fP"
-Comme ci-dessus, mais la recherche des motifs est effectuée sans tenir 
-compte de la casse.
-.TP
-.B include "\fIfichier_de_syntaxes\fP"
-Lit le fichier \fIfichier_de_syntaxes\fP contenant une liste 
-autosuffisante de définitions de syntaxes. Ce fichier ne doit contenir 
-que des commandes \fBsyntax\fP, \fBcolor\fP et \fBicolor\fP.

+.SH EDITING
+Entering text and moving around in a file is straightforward: typing the
+letters and using the normal cursor movement keys.  Commands are entered
+by using the Control (^) and the Alt or Meta (M\-) keys.
+Typing \fB^K\fR deletes the current line and puts it in the cutbuffer.
+Consecutive \fB^K\fRs will put all deleted lines together in the cutbuffer.
+Any cursor movement or executing any other command will cause the next
+\fB^K\fR to overwrite the cutbuffer.  A \fB^U\fR will paste the current
+contents of the cutbuffer at the current cursor position.
+.PP
+When a more precise piece of text needs to be cut or copied, one can mark
+its start with \fB^6\fR, move the cursor to its end (the marked text will be
+highlighted), and then use \fB^K\fR to cut it, or \fBM\-6\fR to copy it to the
+cutbuffer.  One can also save the marked text to a file with \fB^O\fR, or
+spell check it with \fB^T\fR.
+.PP
+Since nano-2.7.0, text can also be selected by holding Shift and moving the
+cursor with the arrow keys.  Holding down the Alt key too will increase the
+stride.
+.PP
+The two lines at the bottom of the screen show the most important commands;
+the built-in help (\fB^G\fR) lists all the available ones.
+The default key bindings can be changed via the .nanorc file -- see
