+GNU nano 1.3.8 - 2005.06.30
+- General:
+	- Miscellaneous comment fixes. (DLR)
+	- Various #include fixes.  Since proto.h includes nano.h, only
+	  include the former in source files.  Also add an #include
+	  guard to proto.h, and make the config.h #include in nano.h
+	  match the config.h #includes everywhere else. (DLR)
+	- Change all hardcoded instances of 128 bytes to MAX_BUF_SIZE,
+	  and #define MAX_BUF_SIZE as 128 in nano.h. (DLR)
+	- Display the key to go to the previous strings in the
+	  search/replace history as "^P" instead of "Up".  This makes
+	  mouse clicks work properly on it.  Changes to shortcut_init(),
+	  help_init(), nanogetstr(), and do_statusbar_input(). (DLR)
+	- Update the Free Software Foundation's mailing address in
+	  various comments. (DLR)
+	- Add the ability to open a file on a specified column as well
+	  as a specified line, by allowing an argument of the form
+	  +LINE,COLUMN.  New function parse_line_column(); changes to
+	  shortcut_init(), main(), do_gotoline() (renamed
+	  do_gotolinecolumn()), do_gotoline_void() (renamed
+	  do_gotolinecolumn_void()), nano.1, and nano.texi. (DLR,
+	  suggested by PFTank)
+	- Overhaul the history code to work more consistently, and clean
+	  up various parts of it.  New function history_has_changed();
+	  changes to load_history(), writehist(),
+	  thanks_for_all_the_fish(), history_init(), find_node()
+	  (renamed find_history()), update_history(),
+	  get_history_older(), get_history_newer(),
+	  get_history_completion(), do_search(), do_replace(),
+	  nanogetstr(), and statusq(); removal of remove_node() and
+	  insert_node(). (DLR)
+	- Remove all instances of charcpy() and replace them with
+	  strncpy(), since there's no way to be sure that a charcpy()ed
+	  string will always be properly null-terminated, and strcpy()'s
+	  null termination is the only difference between it and
+	  charcpy(). (DLR)
+	- When using a backup directory, make sure all the filenames
+	  written are unique by using get_next_filename() when
+	  necessary.  Changes to get_next_filename(), write_file(),
+	  die(), usage(), nano.1, nanorc.5, nanorc.sample, and
+	  nano.texi. (DLR, suggested by James Collings)
+	- Rework the file-writing routines so that they can work
+	  properly with already-opened files, such as the
+	  mkstemp()-created files used by the spell-checking code.
+	  Changes to safe_tempnam() (renamed safe_tempfile()),
+	  write_file(), write_marked(), die(), do_spell(), and
+	  do_exit(). (DLR)
+	- Remove the -R/--regexp command line option and enable the
+	  toggle at the search prompt in tiny mode, as it already
+	  allows the prepend and append toggles at the search prompt.
+	  For consistency, rename TOGGLE_REGEXP_KEY to NANO_REGEXP_KEY,
+	  and move it out of the toggles block to where NANO_PREPEND_KEY
+	  and NANO_APPEND_KEY are.  Also, change the short command line
+	  option for --restricted from -Z to -R.  Changes to
+	  shortcut_init(), usage(), main(), search_init(), nano.1,
+	  nano.texi, etc. (DLR)
+	- Various cleanups and improvements in chars.c.  Remove some
+	  unnecessary w?ctype wrappers and variables; change the wctype
+	  wrappers to take wint_t instead of wchar_t to match the
+	  functions they wrap; rename some functions for consistency;
+	  add functions to detect blank characters in a string, for use
+	  in rcfile option parsing; and don't count matches between
+	  valid and invalid multibyte sequences anymore, as it causes
+	  problems when doing a replace.  New functions
+	  is_valid_mbstring(), has_blank_chars(), and
+	  has_blank_mbchars(); changes to is_alnum_mbchar(),
+	  is_blank_char() (renamed nisblank()), is_blank_mbchar(),
+	  is_blank_wchar() (renamed niswblank()), is_cntrl_wchar(),
+	  control_rep(), control_mbrep(), make_mbstring() (renamed
+	  make_valid_mbstring()), mbstrncasecmp(), mbstrcasestr(),
+	  mbrevstrcasestr(), etc.; removal of is_alnum_char() and
+	  is_alnum_wchar(). (DLR)
+	- Implement word count via Meta-D at the main window.  Note that
+	  this is disabled when NANO_SMALL is defined.  Also, convert
+	  all word detection functions to use the same wrapper function
+	  for ease of maintenance, and make them return more
+	  information.  New functions is_punct_mbchar(),
+	  is_word_mbchar(), do_next_word_void(), do_prev_word_void(),
+	  and do_word_count(); changes to shortcut_init(),
+	  do_next_word(), do_prev_word(), is_whole_word(),
+	  do_statusbar_next_word(), and do_statusbar_prev_word(). (DLR)
+	- Fix #ifdefs so that nano compiles with NANO_SMALL defined and
+	  DISABLE_TABCOMP undefined.  Changes to revstrstr() and
+	  free_charptrarray() (renamed free_chararray()). (DLR)
+	- Change the wctype wrappers to take wchar_t's again, as they
+	  still work the same way with them.  This also fixes
+	  compilation on Mac OS X 10.4.1, which doesn't seem to define a
+	  wint_t type. (DLR, found by Emily Jackson)
+	- Add the ability to convert typed tabs to spaces using
+	  the -E/--tabstospaces command line options, the "tabstospaces"
+	  rcfile option, and the toggle Meta-Q (since QBasic did this by
+	  default :)).  Note that this doesn't affect tabs entered using
+	  verbatim input, and that it's disabled when NANO_SMALL is
+	  defined.  Also, change the short command line option for
+	  --backupdir from -E to -C.  Changes to toggle_init(), usage(),
+	  do_tab(), main(), nanorc.sample, nano.1, nanorc.5, and
+	  nano.texi. (DLR, suggested by many people)
+	- Change the CONSTUPDATE, REVERSE_SEARCH, and SMOOTHSCROLL flags
+	  to the CONST_UPDATE, BACKWARDS_SEARCH, and SMOOTH_SCROLL
+	  flags, respectively. (DLR)
+	- Change the SMOOTHSCROLL flag to the SMOOTH_SCROLL flag. (DLR)
+	- Change the NO_UTF8 flag to the USE_UTF8 flag, and reverse its
+	  meaning. (DLR)
+	- Add rcfile options "casesensitive" and "backwards", to do
+	  case sensitive and backwards searches by default.  Changes to
+	  nanorc.sample and nanorc.5. (DLR)
+	- Since the DISABLE_CURPOS flag is only used in winio.c, reduce
+	  it to a static bool there.  Changes to statusbar() and
+	  disable_cursorpos(). (DLR)
+	- Add -U/--quickblank option and a "quickblank" rcfile option to
+	  blank the statusbar after 1 keystroke instead of 25.  Note
+	  that this obviously has no effect when constant cursor
+	  position display is turned on, and that this is disabled when
+	  NANO_SMALL is defined.  Changes to usage(), main(),
+	  statusbar(), nanorc.sample, nano.1, and nanorc.5. (DLR,
+	  suggested by CHAO Wei-Lun)
+	- Add support for case insensitive expression matching when
+	  using color syntax highlighting, via the "icolor" directive,
+	  and add it to those regexes that can use it.  Changes to
+	  parse_colors(), parse_rcfile(), nanorc.sample, and nanorc.5.
+	  (Brand Huntsman, minor tweaks by DLR)
+	- Add various type changes to avoid problems on systems where
+	  int and ssize_t are different sizes.  Make filestruct->lineno
+	  a ssize_t (so that we can avoid negative line numbers at the
+	  "Go To Line" prompt), current_y a ssize_t (in order to hold
+	  the maximum difference between two filestruct->lineno's),
+	  totlines a size_t, and change related variables to match.
+	  (DLR, initial problem with parse_line_column() found by Mike
+	  Frysinger)
+	- Rework the credits handling to display Florian König's name
+	  properly whether we're in a UTF-8 locale or not, and without
+	  requiring a massive function that we only use once.  Changes
+	  to do_credits(); removal of make_valid_mbstring(). (DLR)
+- chars.c:
+  make_mbstring()
+	- Change erroneous ENABLE_EXTRA #ifdef to NANO_EXTRA to fix a
+	  compilation problem when --enable-nanorc isn't used and
+	  --enable-extra is. (DLR)
+- color.c:
+  update_color()
+	- Use mbstrcasecmp() instead of strcasecmp(), so that UTF-8
+	  color syntax names are properly detected. (DLR)
+- cut.c:
+  cut_line()
+	- Set placewewant properly after cutting a line, to avoid a
+	  problem where the screen won't be updated if (a) we're not on
+	  the first page when we cut the line, and (b) immediately after
+	  we cut the line, we hit End to move to the end of the line
+	  after it. (DLR)
+- files.c:
+  read_line()
+	- Rename variable prev to prevnode to avoid confusion. (DLR)
+	- Rename variable len to buf_len, for consistency. (DLR)
+  load_open_file()
+	- Remove an unneeded clearok(FALSE). (DLR)
+  get_next_filename()
+	- Use an unsigned long instead of an int for the number
+	  prepended to the filename. (DLR)
+  do_insertfile()
+	- Set i to 0 when we get a filename via the file browser, so
+	  that it's read in properly when we exit the file browser.
+	  (DLR)
+  open_prevnext_file()
+	- Move up a misplaced assert. (DLR)
+	- Rename variable next to next_file, to avoid confusion. (DLR)
+  write_file()
+	- Since lineswritten is a size_t, print its value as an unsigned
+	  long instead of an unsigned int. (DLR)
+	- Declare the size_t i only in the loop where it's used. (DLR)
+  diralphasort()
+	- Use mbstrcasecmp() instead of strcasecmp(), so that UTF-8
+	  filenames are sorted properly. (DLR)
+  cwd_tab_completion(), browser_init()
+	- Rename variable next to nextdir to avoid confusion. (DLR)
+  input_tab()
+	- Since list is a bool, set it to FALSE instead of 0. (DLR)
+	- Add multibyte/wide character support, so that we don't end up
+	  with a string that contains only part of a multibyte
+	  character during tab completion. (DLR)
+	- Rename variable buflen to buf_len, for consistency. (DLR)
+  do_browser()
+	- Don't treat NANO_CANCEL_KEY as NANO_EXIT_KEY anymore, for
+	  consistency. (DLR)
+	- When displaying "(dir)" in the available screen space, make
+	  sure that the string it's stored in is always null-terminated.
+	  (DLR)
+	- Rename variable selectedbackup to old_selected, for
+	  consistency. (DLR)
+	- Make mouse clicks in the browser window work properly when the
+	  MORE_SPACE flag is set. (DLR)
+	- Make foo_len a size_t instead of an int. (DLR)
+  save_history()
+	- Properly save history when we're in view mode. (DLR)
+- global.c:
+  shortcut_init()
+	- Move the "Refresh" and "Exit" shortcuts to the beginning of
+	  the help browser shortcut list, for consistency. (DLR)
+	- Remove unnecessary "Refresh" placeholder in the file browser
+	  shortcut list. (DLR)
+	- Allow the mark to be used in view mode, as Pico does. (DLR)
+	- Clarify the description of ^X when --enable-multibuffer is
+	  used. (DLR)
+	- Change the description of the Meta-B toggle at the search
+	  prompt from "Direction" to "Backwards", for consistency. (DLR)
+  toggle_init()
+	- Clarify the descriptions of M-C and M-L. (DLR)
+	- Reorder the toggles to put more toggles with similar functions
+	  together. (DLR)
+  thanks_for_all_the_fish()
+	- Remove free_toggles() and move its code here verbatim, as it's
+	  only called here anyway. (David Benbennick)
+	- Fix the code to free all open file buffers to work properly
+	  with the previous overhaul of the multibuffer code instead of
+	  going into an infinite loop. (David Benbennick)
+	- Add additional checks for variables' not being NULL before we
+	  try to free them, to avoid assertion failures. (DLR)
+- nano.c:
+  die()
+	- Rename variable ret to retval for consistency. (DLR)
+	- Tweak the message displayed when a backup file can't be
+	  written, so as to not duplicate a translated string. (DLR)
+	- If the current filestruct's been partitioned, unpartition it
+	  before saving the associated file. (DLR)
+  resize_variables()
+	- Use charset() instead of memset() to initialize hblank. (DLR)
+  copy_filestruct()
+	- Rename variable prev to copy to avoid confusion. (DLR)
+  print1opt_full()
+	- If desc should be empty, allow it to be NULL instead of
+	  "", since the latter is not necessarily translated as "".
+	  (DLR, found by Jordi)
+  usage()
+	- Add missing N_() around one message, so that it isn't
+	  erroneously translated twice. (DLR)
+	- Remove inaccurate default listed for -Q/--quotestr. (DLR)
+  version()
+	- Add --enable-utf8 to the displayed compilation options, put
+	  the options in alphabetical order, and handle --enable-tiny
+	  the same way as all the other options. (DLR)
+  do_tab()
+	- Remove unneeded variable kbinput. (DLR)
+  do_int_spell_fix()
+	- Display highlighted misspelled words using display_string(),
+	  as do_replace_loop() does. (DLR)
+  do_alt_speller()
+	- Replace a set_modified() with SET(MODIFIED) to avoid an
+	  unnecessary update, and remove an unneeded clearok(FALSE).
+	  (DLR)
+	- Move the spell checking error handling block down and refactor
+	  it so that we go back into curses mode, reinitialize the
+	  terminal, turn the cursor back on, and turn the mark back on
+	  if necessary before returning the error message. (DLR)
+  do_spell()
+	- If the spell-checker printed any error messages onscreen, call
+	  total_refresh() to make sure they're cleared off. (DLR, found
+	  by CHAO Wei-Lun)
+  find_paragraph()
+	- Reset placewewant as well as current_x to 0, in order to avoid
+	  a potential screen update problem. (DLR)
+  do_justify()
+	- Save placewewant, and restore it if we unjustify, in order to
+	  avoid a potential screen update problem. (DLR)
+  do_output()
+	- Properly allow wrapping when we insert a tab, for consistency.
+	  (DLR)
+	- Don't set current_len until after it's been asserted that both
+	  current and current->data aren't NULL. (DLR)
+  do_toggle()
+	- Properly treat color syntax highlighting as enabled by
+	  default, and only treat wrapping as enabled by default when
+	  DISABLE_WRAPPING isn't defined. (DLR)
+  disable_extended_input()
+	- Disable extended output processing as well as extended input
+	  processing, and rename to disable_extended_io(). (DLR)
+  disable_flow_control(), enable_flow_control()
+	- Only turn off flow control on output, as it might be needed
+	  for input on slow terminals. (DLR)
+- nano.h:
+	- Add macro charset(), a wrapper that calls memset(). (DLR)
+	- Readd #defines for the isblank() and iswblank() equivalents.
+	  (DLR)
+	- In the colortype struct, make bright a bool instead of an int,
+	  for consistency. (DLR)
+- proto.h:
+	- Add missing NANO_SMALL and HAVE_REGEX_H #ifdefs around the
+	  do_find_bracket() prototype. (DLR)
+- rcfile.c:
+  color_to_int()
+	- Since colorname's being NULL is handled elsewhere now, assert
+	  that it isn't NULL at the beginning of the function. (DLR)
+  parse_colors()
+	- Properly parse a background color without a foreground color.
+	  (DLR)
+	- Properly generate an error if we get a color directive without
+	  a regex string. (DLR)
+  parse_rcfile()
+	- Properly generate an error if we get an invalid multibyte
+	  string for an option, instead of working around it. (DLR)
+	- Use has_blank_mbchars() to check for blank characters in the
+	  "punct" and "brackets" options, and clarify the error message
+	  displayed when we find blank characters. (DLR)
+- search.c:
+  do_gotoline()
+	- Properly show an error message if we try to go to line 0,
+	  since the first line in the file is 1. (DLR)
+	- Start the search for a line from fileage instead of current
+	  (again). (DLR)
+  replace_regexp()
+	- Rename variables create_flag and new_size to create and
+	  new_line_size, for consistency. (DLR)
+	- Make new_line_size, search_match_count, and i size_t's, for
+	  consistency. (DLR)
+  replace_line()
+	- Make new_line_size and search_match_count size_t's, for
+	  consistency. (DLR)
+  do_replace_loop()
+	- When moving to the next match, update the screen using
+	  edit_refresh() instead of edit_redraw(), as the latter won't
+	  work properly when we've replaced one or more instances of a
+	  string in copy and haven't yet updated current->data to match
+	  copy. (DLR)
+  do_find_bracket()
+	- Miscellaneous cleanups: rename variables for consistency, and
+	  save the search direction and regexp setting in two bools
+	  instead of one flags variable. (DLR)
+- utils.c:
+  num_of_digits()
+	- Use a size_t instead of an int, and rename to digits(). (DLR)
+  align()
+	- Rename variable strp to str for consistency. (DLR)
+- winio.c:
+  do_statusbar_output()
+	- Don't set answer_len until after it's been asserted that
+	  answer isn't NULL. (DLR)
+  display_string()
+	- Avoid a memory corruption problem by allocating enough space
+	  for len plus a trailing multibyte character and/or tab. (DLR)
+	- Don't check for multicolumn characters if the NO_UTF8 flag
+	  isn't set. (DLR)
+	- Free buf_mb when we're done using it. (DLR)
+  nanogetstr()
+	- Rename variable def to curranswer to avoid confusion. (DLR)
+	- Only declare and use the tabbed variable if DISABLE_TABCOMP
+	  isn't defined. (DLR)
+	- Refactor to replace unnecessary variable answer_len with
+	  curranswer_len, and hence avoid an assertion failure involving
+	  the former. (DLR)
+  statusq()
+	- Rename variable which_history to history_list, for
+	  consistency. (DLR)
+	- Rename variables def and ret to curranswer and retval to avoid
+	  confusion. (DLR)
+	- Call wnoutrefresh(bottomwin) after getting an answer and
+	  blanking out the statusbar, to make sure that the blanking is
+	  done.  This fixes a problem where the statusbar is not
+	  properly blanked after using the "Go To Line" prompt with the
+	  NO_HELP flag set. (DLR)
+  titlebar()
+	- Use actual_x() to calculate the number of characters VERMSG
+	  takes up, in case it's UTF-8. (DLR)
+  do_cursorpos()
+	- Properly display the value of totsize as unsigned. (DLR)
+	- If constant is TRUE, only display the cursor position when
+	  disable_cursorpos is FALSE.  Don't refuse to display it when
+	  the cursor position hasn't changed, as that doesn't always
+	  keep it properly updated. (DLR, found by Mike Frysinger)
+  do_help()
+	- Don't treat NANO_CANCEL_KEY as NANO_EXIT_KEY anymore, for
+	  consistency. (DLR)
+  statusbar()
+	- Set statusblank to 25 instead of 26, to match current Pico.
+	  (DLR)
+  edit_redraw()
+	- Make do_refresh a bool instead of an int. (DLR)
+  do_yesno()
+	- Allow refreshing the screen via Ctrl-L, as Pico does. (DLR)
+	- Add a missing assert, and use actual_x() to calculate the
+	  number of characters buf takes up, in case it's UTF-8. (DLR)
+	- Get input from bottomwin instead of edit, so that the cursor
+	  isn't erroneously put in the edit window while we wait for an
+	  answer. (DLR)
+	- Call wnoutrefresh(edit) to make sure that the edit window is
+	  refreshed before we get input, as statusq() does. (DLR)
+  total_redraw()
+	- Simplify to just call wrefresh() on curscr, which updates the
+	  entire screen in one function call without moving the cursor
+	  from the window it's currently in. (DLR)
+	- When using slang, use SLsmg_touch_screen() and SLsmg_refresh()
+	  to update the screen, as slang doesn't define curscr. (DLR)
+  do_replace_highlight()
+	- Use waddch() instead of waddstr() to display a space when we
+	  have a zero-length regex. (DLR)
+	- Rename variable highlight_flag to highlight, for consistency.
+	  (DLR)
+  do_credits()
+	- Save the keystroke that breaks us out of the credits (if any)
+	  and put it back so that it isn't lost.  This is especially
+	  needed if the keystroke is part of a multibyte character.
+	  (DLR)
+- nano.1:
+	- Clarify and consolidate the descriptions of --fill and
+	  --tabsize. (DLR)
+- nanorc.5:
+	- Update the description of how the "color" regex works. (DLR)
+	- Clarify descriptions of the characters that aren't allowed
+	  in the "punct" or "brackets" options. (DLR)
+	- Use .B instead of \fB ... \fP where possible, as nano.1 does.
+	  (DLR)
+	- Clarify and consolidate the descriptions of "fill" and
+	  "tabsize". (DLR)
+- nano.texi:
+	- Update the "Feature Toggles" section to match current nano.
+	  (DLR)
+	- Clarify and consolidate the descriptions of --fill and
+	  --tabsize. (DLR)
+- configure.ac:
+	- Minor tweaks to some of the test blocks to avoid XSI:isms.
+	  (DLR, adapted from a Debian patch for GNU ed by David
+	  Weinehall)
+	- Don't refer to the built-in file browser as crappy anymore.
+	  (DLR)
+	- Check for iswpunct() and mbstowcs(). (DLR)
+	- Change the behavior of --enable-extra to only define
+	  NANO_EXTRA, instead of defining both it and
+	  ENABLE_MULTIBUFFER. (DLR)
+	- Check for get_wch() instead of wget_wch() to determine if
+	  there's a wide curses library, as it's a more generic
+	  function. (DLR)
+	- Check for possibly unavailable functions in alphabetical
+	  order. (DLR)
+- doc/faq.html:
+	- Update section 1.1 to mention the current maintainer. (DLR)
+	- Minor capitalization and wording fixes. (DLR)
+	- Update description of --enable-extra, and add missing line
+	  breaks. (DLR)
+- doc/nanorc.sample:
+	- In the "nanorc" regexes, tweak the "color" regex to properly
+	  color a line that specifies a background color without a
+	  foreground color, and update the associated comments. (DLR)
+	- Clarify descriptions of the characters that aren't allowed
+	  in the "punct" or "brackets" options. (DLR)
+	- Update comment referring to --enable-extra. (DLR)
+	- Add "cxx" and "hxx" to the list of extensions that the
+	  "c-file" regexes apply to, and add "warning" and "error" to
+	  them as well. (Mike Frysinger)
+	- Add regexes for assembler files. (Mike Frysinger)
+	- In the preprocessor directives regex string in the "c-file"
+	  regexes, cover more whitespace characters than just " " by
+	  using "[[:space:]]" instead. (Mike Frysinger)  DLR: Extend
+	  this to other regex strings whenever possible.
+	- Move some overly long split-up regex strings that cover
+	  similar areas onto the same line. (DLR)
+	- Add GCC builtins to the "c-file" regexes. (Mike Frysinger)
+	- Simplify the file extension regex for groff. (DLR)
+	- Clarify and consolidate the descriptions of "fill" and
+	  "tabsize". (DLR)
+- Makefile.am, m4/Makefile.am:
+	- Make sure that the files in EXTRA_DIST are in alphabetical
+	  order, and that the lines are wrapped at 72 characters. (DLR)
+- doc/man/fr/Makefile.am:
+	- Set mandir to @mandir@/fr, so French manpages get installed
+	  where they belong (Jordi).
+- THANKS:
+	- Add new translators to the credits.
+
+GNU nano 1.3.7 - 2005.04.10
+- General:
+	- Miscellaneous comment fixes. (DLR)
+	- After (re)initializing the terminal, make sure the cursor is
+	  always turned on.  Changes to do_alt_speller(),
+	  handle_sigwinch(), and main(). (DLR)
+	- Make sure that all references to cut-to-end are left out when
+	  NANO_SMALL is defined.  Changes to cut_to_eol(),
+	  do_cut_text(), and do_statusbar_cut_text(). (DLR)
+- chars.c:
+  make_mbchar()
+	- Remove unneeded assert. (DLR)
+  move_mbleft()
+	- Fix assert to reference the proper variable, so that nano
+	  builds with DEBUG defined again. (Mike Frysinger, found by
+	  Dmitri Vassilenko)
+- files.c:
+  do_insertfile()
+	- Fix problem where going into the help browser at the "Insert
+	  File" prompt would always result in the current answer's being
+	  used as the filename afterward. (DLR)
+  get_full_path()
+	- Rework handling of the results of getcwd() in order to avoid
+	  segfaults if they fail, and to remove uses of the nonportable
+	  GNU extension where passing a size of 0 will get a string as
+	  long as we need. (DLR)
+  do_browser()
+	- Rename variable lineno to fileline to avoid confusion. (DLR)
+  do_browse_from()
+	- Rework handling of the results of getcwd() in order to avoid

+- nano.c:

+	- When calculating allocsize, take multibyte characters into
+	  account, and keep the column number limits consistent. (DLR)
+	- Break htx up into three chunks, in case the string is too long
+	  for the compiler to handle (e.g. an ISO C89 compiler that can
+	  only handle up to 509 characters). (DLR)
+	- Minor wording fixes. (DLR)
+  print1opt()
+	- Don't include longflag if HAVE_GETOPT_LONG isn't defined.
+	  Rename this function to print1opt_full(), leave out the
+	  longflag parameter if HAVE_GETOPT_LONG isn't defined, and make

+	  without the need for a lot of extra #ifdefs. (David
+	  Benbennick)  DLR: Rename print1opt_f() to print1opt_full().
+	- Rework the special case of options that are ignored for Pico
+	  compatibility so that they display more neatly when
+	  HAVE_GETOPT_LONG isn't defined. (DLR)

+	  Benbennick)
+- nano.h:
+	- Define PATH_MAX as 4096 if it isn't defined, as passing a size
+	  of 0 to get a string as long as we need is a nonportable GNU

+	- Make sure that the vsnprintf(foo) call and foo's subsequent

+  titlebar()

+- nanorc.sample:
+	- Fix the description for the whitespace option to mention that

+	- Break up overly long perl and nanorc regexes into separate

+2005.06.30 - GNU nano 1.3.8 floats at its own level.  This release
+		contains several new features.  Among other things, you
+		can now move to a specified column number as well as
+		line number within a file, file backups saved in a
+		backup directory will have unique names, the search and
+		replace history routines should work more consistently,
+		you can get a word count by pressing Meta-D at the edit
+		window, and there's a new -E/--tabstospaces option to
+		convert all typed tabs to spaces (--backupdir's short
+		option has been changed to -C).  In terms of bugfixes,
+		this release contains fixes for minor problems with
+		screen updates, UTF-8 display, and flow control; a fix
+		for a segfault when displaying some lines ending with
+		tabs; better handling of constant cursor position
+		display; improved color parsing in the rcfile; and
+		support for the "Regexp" toggle in tiny mode
+		(-R/--regexp is gone, and --restricted's short option
+		has been changed to -R), among other things.  Enjoy.
+
+2005.04.10 - GNU nano 1.3.7 claws its way to the top.  This release
+		mostly contains bugfixes for the massive amount of new
+		code in 1.3.6.  Among other things, nano builds with
+		debug support again; going into the help browser at the
+		"Read File" prompt no longer kicks you out of the prompt
+		after you exit the help browser; paragraph searching no
+		longer skips over certain cases of single-line
+		paragraphs; the titlebar no longer cuts off some UTF-8
+		strings prematurely; and the text displayed in the help
+		browser is now wrapped as it was in nano 1.2.x, taking
+		UTF-8 support into account.  New features include an
+		--enable/disable-utf8 configure option to explicitly
+		turn detection of UTF-8 support on or off, and sample
+		regexes for C++ as well as C.  Have fun.
