This same pattern can be found repeated in at least ten earlier places
in our project history, btw --- just look for commits using the phrase
"manufactured by cvs2svn to create tag" instead of "to create branch".
The worst example is probably the one for tag REL7_1_BETA, which deletes
70-odd files.
