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.

        * configure.ac, doc/man/Makefile.am - Add check for HTML output support in GNU
          groff.  Fixes Savannah bug #24461: build traps on groff.  Also, add installation
          of html-ized man pages to $datadir/nano/man-html, since we should probably
          install files we went to all the trouble of generating.

        * 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@4367 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

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

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.

	  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

        * 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.
