for things like deleting text.  Will have to go back and force inside functions.
Add check in reset_multis for CNONE type since that's slowing us down and is dumb
to leave out.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4379 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * Add new argument to reset_multis for force redraws without attempting to
          guess whether we need to, force updates when running a non-viewok function.
          New utility function color.c:reset_multis_for_id().  Fixes e.g. incorrect
          highlighting when cutting text.

        * nano.c (precalc_multicolorinfo) - Add debugging so we have a better clue if further
          issues arise.   Also start at the beginning of later lines when trying to match the
          end of a multi-line regex.  Fixes more overly aggressive highlighting found by 
          Mike Frysinger.  Finally, advance to the match end for performance.

        * nanorc.c (parse_include): Do call real_dir_from_tilde() on included
          files in .nanorc, but still avoiding bug #25297.  Fixes ~ and ~user
          specifications for nanorc include files, as reported by Eitan Adler.

        * New option -q, --quiet, rcfile option "quiet" implemented.  Skips printing
          errors about the rcfile and asking user to press enter.  Also, nano should
          now only ask for one enter press when there is an error when not using -q.
          Based on discussion between Eitan Adler and Mike Frysinger.
        * rcfile.c (parse_keybinding) -  Significant cleanups and fixes for
          detecting and reporting errors in key bindings code.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4374 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

          syntax highlting is now too *un*ambitious, causing display glitches when
          deleting a regex boundary.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4373 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * Add more multidata initliazers for new buffers and 'magic lines'.  Fixes segfaults
          with syntax highlighting in new buffers, initially reported by Mike Frysinger.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4372 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

Add alloc_multidata_if_needed() call in edit_draw as the last defense against a crash.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4367 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

Added bug 80 to document segfault when editing near COLS



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4366 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * rcfile.c (parse_include): Abort on being unable to open an included rcfile.  Fixes
          Savannah bug 25490, nanorc: "include"ing a file which doesn't exist causes nano to segfault.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4365 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * More color syntax speedups:  Determine in reset_multis() whether we really need to call
          edit_refresh().  Additional global var edit_refresh_needed() to hopefully reduce  
          repeated calls to the function.  New helper funcs reset_multis_before() and 
          reset_multis_after().



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4364 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

New utility func alloc_multidata_if_needed().



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4363 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * New color precalculation code for mult-line regexes.  New function precalc_multicolorinfo(),
          new structure multidata for keeping track of where regexes start/stop.  More 
          performance improvements forthcoming.

	* nano.c (move_to_filestruct) - properky initialize new fileage for multiswatching, sigh.
	  Fix cut sefaults discovered by Mike Frysinger.

        * nano.c (main): Add support for nano acting like a pager when invoked with - as first   
          file argument.  Not yet perfect (garbles screen state on exit) but it's something. 



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4356 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * files.c (open_file), nanorc.c (parse_include): Don't get_full_path on     
          included rc files, due to it potentially impacting the ability
          to read files in nano's cwd().  Fixes Savnanah bug #25297 reported by Mike 
          Frysinger)

          multi-line regexes but this may not be enough to increase performance.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4351 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * Add interruptability to search functions.  New functions enable_nodelay and
          disable_nodelay and changes to the routines to handle checking for pending
          searches.  Fixes Savnnah bug 24946: Need interrrupt for search.

        * Change funcion definitions to shorts instead of (void *)s.  New mapping function
          iso_me_harder_funcmap().  Fixes compilation complaints with -pedantic, 
          reported by Eitan Adler <eitanadlerlist@gmail.com>.

        * files.c (do_writeout): Add check for file modification when saving
          the file so the user can at least know they may be blowing away changes.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4344 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

          invalid messages will display properly.  Fixes Savannah bug 24507.

Also initialize to_end, because for some reason it seems to be not getting set even when
type == CUT in add_undo (?!)



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4340 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * Remove CUTTOEND as an undo type as it's unneeded, fix u->to_end logic in undo struct.
        * undo.c (update_undo): Don't free cutbuffer if NULL, fix for Savannah bug #24499



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4339 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * cut.c (Add_undo): Save last cut undo information so it can be used for next uncut, fixes
          Savannah bug 24183.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4338 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * rcfile.c, color.c, nano.h: Add new capability for matching a syntax type by the "header" (1st line)
          of a file being edited.  Based on Savannah bug 24197 and inital proof of concept by Dave Geering
          <dgeering@toshiba-tap.com>

        * text.c: Add support for undoing a text uncut.  Split out the undo and redo of a text cut
          in order to avoid code duplication.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4327 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * nano.c: Do call disable_signals at startup regardless, since under cygwin we can't generate
          ^C without it.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4326 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

          issues with --disable-help, especially that do-writeout was treating ^G the same as ^M.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4317 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * configure.ac, color.c, rcfile.c, utils.c: 1st attempt at supporting systems which don't support
          GNU-style word boundaries.  New function fixbounds() to translate from GNU-style to
          BSD-style, autoconf option GNU_WORDBOUNDS.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4315 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * configure.ac, rcfile.c:  Add support for an alternate rcfilename at configure time.  Maybe this
          should become a command line option some day, but I don't see the need currently.  Start of   
          fix for Savannah bug #24128: Add nanorc support to win32 platform.
