I think the patch itself makes sense.  If for some reason the
importer detects that the CVS or SVN history moved a tag, we
either:

    (1) have a way to keep track of the versions of the tag; or
    (2) allow it and make it "last one wins" semantics; or
    (3) ignore it and make it "first one wins" semantics.  

Erroring out complaining that the tag cannot be created, as the
current code does, does not make any sense.

The patch needs to be accompanied with a better commit log
description.  I am guessing that with your change the semantics
would become (2) above (assuming that cvsps or whoever reads the
history of the other side gives events in chronological order),
but you should not force readers of your commit log message to
guess.
