I'd also advocate mikmatch. It's quite good an honestly perhaps the best
thing around. I've however experienced some difficulties when you've got
too many nestings of mikmatch pattern matching. Likely some name/scope
clashes between generated hidden values.

Not 100% perfect, but it really improves the user experience. In this
context, I really do not mind the PCRE dependency at all.
