Yes, I noticed that as a potential problem when I was adding the ::
support, but I didn't worry about it too much since I don't recall
anyone ever reporting it.  Unfortunately, the code is full of
assumptions that the starting and ending revision numbers have the same
number of dots, so there's a lot of rewriting to do.  It's also not
quite as simple as it might seem, since I believe that 1.2:
should also be a valid range, no?  (All revisions with a single dot are
on the trunk, reguardless of the major revision number; on other
branches, the major componenents of the revision number must be exactly
