This completes the fix for Savannah bug #47325.

* 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.
git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4540 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

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.

New nanorc entry "magic" to enable this functionality, nanorc file and man page updates.

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.

deleting a regex boundary.

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().
git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4364 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.
git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4362 35c25a1d-7b9e-4130-9fde-d3aeb78583b8
* 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@4351 35c25a1d-7b9e-4130-9fde-d3aeb78583b8
* 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

* 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.

originally added in 0.2.7, which was apparently in 1999; and one of the
oldest functions in text.c is do_wrap(), which was originally added in
0.3.1, which was apparently in 1999; also, for functions originally
adapted from other sources, add notices from the original files, as we
do with the tab completion functions adapted from busybox
