Now that would match "[Q] newbie (was: Re: [BUG][FIX] Bla)". But not the
"[unix] [fix]" example I gave. I think it's not *that* simple, otherwise I
wouldn't have asked ;-)

But thinking about it, a number of bracketed tags would be something like

	(\[[A-Z -]+\] *)*

so I might try that? Better ideas?
