If yours is the most positive review, there probably won't be one.  :-)

Seriously, though, I'd readily concede that there are different approaches to
solving this problem, and I was hoping for some feedback and suggestions
before I start whacking at the code.  I also have considered the possibility
that although this has been driving me nuts that few others will care--if this
is true, it probably *shouldn't* go in the core libraries.

Yes.  Good point.

Hmm.  Yeah, if it weren't for the value of matching re.match semantics, it
would make a lot more sense for this to be an exception.  As it is, I could
see it going either way.  Or I suppose you could add a flag to determine which
(but ugh).

Thanks for your feedback!
