[Nottingham] PHP RegEx woes

[Michael Simms]

Yeah regex is greedy. What you wanna do is make the regex middle
matching bit be anything that *doesnt* have a [ in it, as I assume this
is for url matching, there wont be a [ in it. That way it will refuse to
match as far as past the start of the next one, so so its only possible
closer can be the closer of the current one.
