Hi George,

Sorry for the delay.  I didn't do much maintenance of my software
during the shutdown.

This will be fixed in the next release.  The work-around until then is
not to use the "+" character (or "*" or "?" or a few others) in your
group names.

The source of the problem is that I failed to escape the "+" character
before checking against the name of the reference group.  The "+"
character was then interpreted in the regular expression sense rather
than as a character in the group name.  Oops!

How interesting that no one, including me, had noticed that until now!
