I see. Yeah, that might work, except that Sizzle is currently very
liberal about quotation marks:
PSEUDO: /:((?:[\w\u00c0-\uFFFF-]|\\.)+)(?:\((['"]*)((?:\([^\)]+\)|[^\2\
(\)]*)+)\2\))?/
I think it's a fairly common misconception that you have to use quotes
within match[3], so at best it would take a lot of re-education and at
worst it would break a lot of code.

p.s. sorry about the tone of my last email. I just re-read what I
wrote (the "how in the world" part, especially), and I think I sounded
like an arrogant bastard. My apologies.
