Hmm... Collapsing whitespace. Going back to the original RE, and what it
probably was meant to be. "A minimum of 175 chars other than [:;] before
the tag closing, with any whitespace ignored."
/(?:\s*[^\s:;<]){175}/
What about that, then? :) Unlike the original, this one simply swallows
any whitespace and operates on a minimum number of non-whitespace, non-
style definition syntax (very basic set). Whereas the original RE
happily would have accepted 1*175, up until 20*175 chars of pure
whitespace. Hardly gibberish, but just a waste of bandwidth. ;)
