Thanks so much for the review, guys.  I should have mentioned in this
patch that the my regex skills are very weak, and that it was surely
incomplete.  I always forget about the is: prefix as well.

Every time I think I start to understand regex I am reminded that it's
black magic and I really know nothing.  For instance, I am not familiar
with "<" or ">", although they appear to be a "word" boundaries
(although I'm not sure how "word" is defined).  Also, why is all the \\
(double?)  escaping needed?  I'll certainly take your word for it,
though.

After staring at this for 10 minutes I think I'm getting the extra bits
here.  It matches an initial \", and then a second at the end if the
first matched.  That's clever.  Why 

  \\>\\2

instead of

 \\2\\>

?

I'm definitely confused by why so much apparent escaping is needed,
though.

Very much looking forward to it!
