It's a hangover from old cvs which I think got removed in 2.5.04 but I'm 
not sure (try a testing version).  If cvs doesn't know about a tag it'll 
scan the entire repository looking for it... which isn't a win really 
and should have been got rid of a while ago.

evs of course knows which tags exist in which modules automatically so 
doesn't have the issue.
