I retract that statement. For some reason, if a file of the same name
existed in the previous trunk, and you invoke the diff from show log of
the current trunk, then the diff correctly shows the differences between
the two revs of the correct file (even though it lived in the branch
back in the revs that are being diffed). But for files that live in the
current trunk, came from the old branch and didn't have an equivalent in
the old trunk, the failure is the same. If that description is unclear
(I suspect it is) then I can do another script to demonstrate.
