        * 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.

        * 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().

        * 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 (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.

        * 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

          the file so the user can at least know they may be blowing away changes.

type == CUT in add_undo (?!)

          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.

        * 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.

        * 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.

        * 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.

	* files.c (write_file): Check exit code of fclose(), since in certain out of space conditions the OS will
	  happily report successful fwrite()s until you try and close the file.  Fix for Savannah bug
	  #24000: no free space on partition - nano claims successful write - file empty

          mistakenly think this is an update when it's really an add.  Also
