I never said it did.  :-)

CVS won't allow removing tagged revisions if you use the "new" inclusive
range syntax, but it neglects to check for magic branch tags.  That is a
bug that I am fixing.  Only checking when using the new syntax is an
obsolescent feature (the manual warns that it could change in the
future) that I think is long overdue for change.  Changing the code is
easy but it has unexpectedly large ramifacations on the test suite.
