What's worse, rtag has the same problem, because it ignores things in
the Attic directory! Ah, the stupid Attic hack.
This problem does not occur in Meta-CVS right now, because it
currently does not support merging from the trunk; so the tags it
applies with rtag are always done with -F and -r <branch>. This does
move the tags on removed files forward to their dead revisions.
But guess what? There is a workaround for the main trunk. If you use
rtag -r HEAD -F mytag module
then it *does* push the tag forward onto the 1.2 dead revision! Only
if you don't specify a revision does it ignore the Attic files. This
is acceptable; I don't care for having the tag removed; moving it to
the dead revision is okay. If I add to Meta-CVS the support for
merging from HEAD up to a branch, then this little trick will help.

There is also the -a option of rtag, which will remove the tag from
deleted files. I think that if you combine -a and -F, you get the
behavior you are looking for.
