[Nano-devel] Color patch

[delta]

http://bespin.org/~qz/nano-1.2.2-color.patch

Changes made by this patch:
- Errors when a syntax name is redefined.
- Uses syntax override when present even when a definition
  exists for the file extension.
- New 'default-syntax' directive, applied to files that don't
  match a syntax.
- New 'icolor' directive for case-insensitive matches,
  same format as color directive.
- New 'include' directive based on the nanovarcinsert patch.
  Modified to only include files containing color and icolor
  directives. Errors when called outside of a syntax directive.
- New '-d' and '--display-syntax' options to display syntaxes for
  testing purposes and then quit. Displayed in a grep'able format
  `nano -d |grep "^html:"`
- Only stores compiled regular expressions for syntaxes that are in use.

I formatted new error messages as "-- the error --" so they can be
easily found and changed if needed.

The new regular expression code reduced the memory footprint by 1.3meg
with my nanorc file. I used it to write most of the code in this patch
and I had no problems. This patch does not fix the regexec() memory
leak.
