Any thoughts on this?  These are becoming more common in the code I work
on and some colleagues and I would like support, since they can destroy 
fontification of the rest of the buffer.  I'm hesitant to try and do it
myself because of the famed difficulty of cc-mode.  :-(  But I'm willing
to try if someone has ideas.
