        * winio.c (edit_update) - properly update edittop when using soft wrapping.

        * Initial soft line wrapping implementation.  Command line flags
          -$ or --softwrap.
        * nano.c, text.c: Clean up some fprintf warnings in debug mode due to printing

git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4397 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

Add in rcfile support for undo since it would be bad to overly punish the masochists who want to try it out and hopefully submit bug reports.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4396 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

	* nano-regress: Small tweaks
	* Change undo code to off unless unabled via a command line option (-u/--undo).  Until this code
	  stabilizes this is the only responsible way to treat it.

- Remove a debug line I left in
- Fix undo line split uglyness.  Still not perfect but switching work envs.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4390 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

First pass at fixing the line splitting undo since it's currently broken beyond belief.
I believe more is broken but committing will motivate me to get closer to a real fix :)

          and 2.4 series for things which are feasible.

        * configure.ac: Add check for whether _XOPEN_SOURCE_EXTENDED is needed for 
          curses to work w/color.  Fixes compilation on HP-UX with older GCC, 
          reported by jay.krell@cornell.edu.

	* fix some redefinitions causing compiler warnings, from Eitan Adler.  Other
	  (hopefully) fixes for uncasted malloc()s, reported by the same.

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.

        * 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.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4377 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * 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.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4376 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * 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.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4375 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * 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.
