also freeing the regexes for libmagic results and headerlines.

	* color.c (color_update): Add check for whether the file even exists
	  before we try to run the magic check on it.  Fixes error messages to stderr
	  when reading in files that don't exist, reported by Mike Frysinger.

        * color.c (color_update): Remove unneeded debugging message from
          libmagic commit.  Fixed extra messages going to stderr reported by Mike Frysinger.

        * color.c (nfreeregex): Fix that we were trying to set the pointer passed by value
          to NULL.  Fixes crashes on file save reported by Ken Tyler and Matthieu Lejeune.

        * Initial libmagic implementation, adapted from Eitan Adler <eitanadlerlist@gmail.com>.
          New nanorc entry "magic" to enable this functionality, nanorc file and man page updates.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4528 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * Update documentation for 2.2 features including sample nanorc file, texinfo
          file, man pages, UPGRADE file, and update copyright noticed for the current year.

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.

        * 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.

          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 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

        * 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. 



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

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

        * 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>

        * 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.
