Hi,

This patch, against emacs-unicode-2/lisp/progmodes, enhances cc-mode's
handling of Objective-C:

- auto-indent method calls by colons (like XCode)
- syntax highlighting for method calls
- add more constants for font-lock highlighting

The original version was written by Michael Weber, and I updated it
for GNU emacs-21+.  I'd be interested in getting it into the emacs
distribution as it would provide a better out-of-box environment for
Objective-C developers.  I'm unsure if that means it needs to go into
cc-mode's own tree?  I sent a couple of messages a while ago to
cc-mode's own list but they may have been drowned in spam.
(http://article.gmane.org/gmane.emacs.cc-mode-general/2692)

(If there are any Obj-C devs using emacs on this list, perhaps they
could try the patch -- it's also built-in to the Emacs.app
distribution at http://emacs-app.sf.net/ )
