Thanks, John!

Yes, I had posted the wrong function originally.  So much for proof 
reading, eh?

This matches everything from the word boundary to the parentheses, which 
is a bit much.  A quick modification of removing the escaped '.' fixed 
things right up:

	nil '(("\\(\\(?:\\sw\\|\\s_\\)+\\)("

Now it appears to match only the characters and underscores to the left 
of the opening parentheses to either the dot or the word boundary.

Much appreciated and the differences in the regex lines will give me
something to study.

My apologies for not replying sooner.  I had originally posted the 
question to the gnu.emacs.help newsgroup and never saw any replies in 
it.  Today I found the gmane.emacs.help groups with my OP and the 
replies, so now I am trying to follow up through Gmane.
