[php] & [code] fixed width like here

[base]

having searched for this hack, and not being able to find it, i was wondering if someone could point me in the direction of the hack that allows the [php] and [code] boxes to be of a fixed width, as they are here at vb.org.

if it hasn't been released yet, is there any chance that it would be anytime soon? i'm getting tired of the [code] and [php] tags pushing the postbits out of whack
