        * winio.c (edit_update) - properly update edittop when using soft wrapping.
          Fixes lack of centering for searching for off-screen answers, found by
          Hannes <mr_creosote@mutantwatch.de>.

        * global.c (shortcut_init): Fix up/down keys not responding in the file browser,
          discovered by Hannes <mr_creosote@mutantwatch.de>.
        * move.c (do_up) - Fix another scrolling issue with softwrap when the

        * Attempt to check file writability and emit a warning on the status bar
          if nano doesn't think the file can be written to.  Feature originally
          requested by Damien Jolders <madamien@skullsquad.com> et al.

        * Fix more soft wrapping issues, particularly with soft scrolling,
          discovered by Hannes <mr_creosote@mutantwatch.de>.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4405 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

	* Fix issue with soft wrapping not displaying the last character of each line,
	  fixed bug discovered by Hannes <mr_creosote@mutantwatch.de>.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4404 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * 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
          a size_t without using the zd specifier.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4402 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

	* New global flag implementation courtesy of Adam Wysocki <gophi@arcabit.pl>, allows
 	  previous undo flag to be implemented consistent with other flags.

	* text.c (undo_cut, redo_cut): Don't actually try and undo/redo an empty cut, i.e. the magicline. 
	  Fixes crash on cutting last line discovered by Eitan Adler <eitanadlerlist@gmail.com>.



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.

Hate to piecemeal these fixed but system unstability is teh suck.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4392 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

Change message for line split to line wrap, since split ~= break



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4391 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- 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 :)



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4389 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

        * 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.

	* rcfile.c (parse_keybinding) - Define a var before tryung to use it.  Whoops!
	* 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.



git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4378 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.



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

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.

	  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.
