Cough.

Unless you have Asperger's or some other similar condition,
I don't think there's any difficulty in understanding what
Lasse wrote, and its implications.

Well, I already showed that that isn't so. And if an expert
such as yourself can't make an obvious regexp match the
specification, then I think there is a lesson to be learnt
there. Regexps can be powerful, terse, and convenient, but
they can be very tricky things to get right, even the simple
ones. --Antony

P.S. Having said what I've said, I think it's a good thing
that its regexps are somewhat limited compared to some other
implementations.
