- winio.c:edit_add() - Add in the necessary regfree() calls to stop nano from leaking memory like a sieve when using color syntax highlighting :-)

- More cleanups with DISABLE flags, better free_shortcutage and free_toggle, and get rid of unnecessary variable decls with NANO_SMALL in shortcut_init() by David Benbennick

General - Added separate regex variable (color_regex and colormatches) so that color syntax and regex search/replace can coexist

- winio.c:do_cursorpos() - Rewritten to show col place as well as charcter place, without needing an entirely separate flag


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1067 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- General - New flag RELATIVECHARS to show column positino relative to the current line instead of the current file.  New flag -C, --relative, changes to do_cursorpos()


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1046 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- General - Added multiple-line regex support.  Format in .nanorc is start=regex end=regex.  Cleaned up nanorc:parse_colors(), added parse_next_regex(), changes to edit_add in winio.c(), changes to colortype, cleaning up some old cruft

- winio.c:update_line() - set realdata check to >= 1 && <= 31, lack of > 0 check screwed high ascii chars


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@937 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- winio.c:update_line() - back out check for (realdata[i] < 32) as it will screw high ascii characters

git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@921 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

Two fixes, create new colorstrings array for each regex, allows proper order of highlighting, second make color work with the marker

git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@912 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

Preliminary syntax highlighting support.  New functions colortoint() and parse_color() in rcfile.c, new code in edit_add() in winio.c to actually do the highlighting.  It's not even close to pretty yet :P


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@910 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

Changed header comments to say "version 2" instead of "version 1" as the COPYING file is actually version 2 of the GPL (bug noticed by Jordi Mallach)
