I agree, Ronald. As a matter of fact, when I saw Richard's problem the
first time around, I went for the /e solution right away (more for
cleanliness of logic than speed considerations), and used (.+?).

At the time I was running ActiveState (a recent build), and although it's
been happy with non-greedy RE's before, this one it barfed on, and I e
never did figure out why.

It's a valid point, and would have to be addressed in production code.
