If you tag twice, then CVS emits a warning for all files in which the
tag exists already and leaves it alone.

Suppose b2 contains a few files that are not in b1. 

You do

    cvs rtag -r b1 A module

Okay, so all the files at the tip of branch b1 have the tag now. Then
you do:

    cvs rtag -r b2 A module

now any files which are present in b2, but not in b1, get the tag. 

There is a -F option you can use to force the retagging.  I *think*
that if -F is combined with -r, this will also *remove* the tags from
files that are not in the new file set. 

I seem to recall that there is a bug with this if there is no -r option
(main trunk HEAD is *implicitly* selected as the revision). Probably
because the Attic optimization is applied. The workaround is to use 
``rtag -F -r HEAD'' when pushing a tag forward on the main trunk, such
that it's correctly removed from any files that were previously
tagged, but have been removed since then.
