At least some of the VTE-based terminals claim to be compatible with
xterm-25color (and set TERM to that value). But they really aren't:
they mishandle the focus-in and focus-out events, for example. So,
catch and discard the corresponding keycodes that nano shouldn't be
seeing at all.
This improves the fix for https://savannah.gnu.org/bugs/?64578.
This allows specifying bindable functions in a string bind by name
instead of by the literal control code or escape sequence to which
they are bound, which makes for a much more readable string bind,
and also allows specifying functions that are not bound to any key.
The opening brace, {, is made into a special symbol inside a string
bind, and each literal occurrence there needs to be escaped as {{}.
This fulfills https://savannah.gnu.org/bugs/?61692.

This does not waste time looking for an end match, which is especially
wasteful when there is none. Also, it makes the coloring behavior more
consistent: any start match will cause coloring of the subsequent text,
no matter whether the user is in the middle of the file or near the end.
Letting the dummy key KEY_FRESH do a full refresh in the tiny version
allows a 'fg' to properly resume after an external SIGSTOP.
(Reminder: the ungetch() is needed in the normal version to prevent
the eating of a keystroke: https://savannah.gnu.org/bugs/?48331.)
With --zero or 'set zero', nano will hide the title bar or the minibar
(whichever is active) and will use all rows of the terminal for showing
the text of the buffer. Only when there is an important message will
it be shown on the bottom row -- until the next keystroke.
This feature can be toggled with M-Z.
The feedback at startup ("Read nnn lines") is suppressed with --zero,
because it disrupts the fullscreen experience (and is hardly useful).
The "Reading..." message then needs to be suppressed too, otherwise
it creates an annoying little flash.
There are still some issues that need to be addressed:
* In the browser, when the highlighted item is on the bottom row, it
will get obscured by the prompt bar or the "Search Wrapped" message.
* In the edit window, when the search occurrence is on the bottom row,
it can get obscured by the "This is the only occurrence" message.
* When tabbing at a prompt shows possible completions, they are shown
a row too low.
When the history file has been created by nano, it will not contain
any duplicate search or replace strings, nor duplicate commands, so
checking for such a duplicate for each read item was a waste of time.
And if the user edited the history file and created duplicates, who
are we to filter them out? They will not cause the history mechanism
to malfunction; they just take a little extra memory.
When a segment of text is extracted, copy any anchors that it has
into the cutbuffer, so that they get saved in the undo item, so that
an undo will put these anchors back on the lines where they were,
instead of leaving an inherited anchor at the top of the segment.
And when text is pasted, clear any anchors in it, so that they will
not travel nor multiply.
This fixes https://savannah.gnu.org/bugs/?61162.
Bug existed since version 5.0, since anchors were introduced.
The documentation (https://www.haiku-os.org/docs/api/libroot.html)
says that BSD extensions are enabled by default, but somehow this
does not seem to be the case on my system. With _DEFAULT_SOURCE
defined, though, src/files.c now compiles fine.
When it is not specified, it defaults to the value for 'titlecolor'.
When not using --minibar, I want the title bar to be blue (as that is
how I've always had it), but with --minibar, I want this mini bar to
be grey, as otherwise it reminds me too much of the prompt bar.
Also, colorize 'set minicolor' as valid in a nanorc file.
This reduces startup time by seven percent (when using the standard set
of syntaxes) when opening just one file that doesn't match any syntax,
and more than ten percent when opening multiple files. It takes some
extra memory, but... not wasting CPU cycles is more important.
This addresses https://savannah.gnu.org/bugs/?56433.
Whenever softwrap was toggled on or line numbers were toggled on/off or
the window was resized, the extra rows per line needed to be recomputed
for ALL the lines. For large files with many long lines this was too
costly.
(This change causes the indicator to have an incorrect size when there
are many softwrapped chunks onscreen, but that will be addressed later.)
This fixes https://savannah.gnu.org/bugs/?60429.
Problem existed since version 5.0, since the indicator was introduced.
In UTF-8 valid multibyte characters are at most four bytes long,
and now that we no longer make use of mblen() and mbtowc() from
the underlying system, we won't get five- or six-byte sequences
mistakenly reported as valid (by glibc). So it is always enough
to reserve space for just four bytes per character.
Set the 'format' of a file only when it has been fully read in,
so that this field can be used to indicate that any later error
message cannot be meant for this buffer.
This fixes https://savannah.gnu.org/bugs/?60269.
Bug existed since commit 6bf52dcc from yesterday.
When opening multiple files and some of them had an error, only the
first message was shown and the others were lost -- indicated only
by three dots. Improve upon this by storing the first error message
for each buffer and showing this message when the buffer is first
switched to.

Now that a search match gets highlighted, the unsuspecting user might
think that the text is selected, because it is colorized the same way
as selected text. Avoid this by colorizing a highlighted search match
with its own specific color, black on yellow by default.
Remarks are about unsurprising things but it's good to give feedback
on them; "mistakes" are unexpected things, and get colored like an
error; and information is something that the user requested and thus
needs to stay on the status bar until the next keystroke.
(Yes, the test is for 6.0, but the bug was actually fixed in 5.9,
as far as I remember -- I just wasn't sure and didn't want to bother
building different versions of ncurses myself.)
Trying to determine which syntax to apply with the help of libmagic
can be a somewhat time-consuming and yet often still fruitless affair.
Therefore using libmagic should not be the default; it should require
an option to tell nano to try using libmagic when it can't determine
the applicable syntax from the file's name or first line.
This is better than having a --nomagic option (and using libmagic by
default), because when the user has 'set nomagic' in their nanorc or
--nomagic in their alias, then switching the use of libmagic back on
is troublesome. But with --magic (and not using libmagic by default),
when nano fails to recognize a file, it is a simple ^X, add -! to the
command line, and restart.
The short form of the option is -! because we have run out of letters.
This addresses https://savannah.gnu.org/bugs/?59028.
With --stateflags (short form: -%) or 'set stateflags', nano reserves
the righthand end of the title bar not for showing "Modified" but for
showing the state of auto-indentation (I), the mark (M), the breaking
of long lines (L), macro recording (R), and softwrapping (S).
When the buffer is modified, this is indicated with a star (*) after
the file name (shown in the center of the title bar).
This fulfills https://savannah.gnu.org/bugs/?57953.
