[cvsnt] Renaming a branch

I guess it depends on the scenario you are facing:

Maybe you need to rename a branch tag that exists only in a single file 
(or few known files) that you are working on. In that case, using the 
'tag' command and specifying a few files seems to be natural. (Even 
wise, if your repository is large enough to make the rtag execution last 
for, let's say, three or five minutes)

Or maybe you need to rename a repository-wide branch... in this case I'd 
certainly go for rtag.
