Oh, I thought that might have been the case. It explains why you were
going through all that trouble with the regexp.

(whitespace-cleanup): Remove a FIXME: the reason for save-match-data
is the call of re-search-forward.
I'm not sure this is a sufficient explanation of why save-match-data is
needed. Usually in Emacs the caller is responsible for saving the match
data, if it needs to. I don't really see the need here.
