[Not disagreeing with Larry; just elaborating]

Case 3 is supposed to work all the time.  CVSROOT/val-tags exists
specifically to let CVS distinguish Cases 2 and 3 (the only other
way would be to recursively search the entire repo for files
containing the requested tag -- obviously a non-starter).  But
val-tags is not always correct; tags that are supposed to be
listed in it aren't always there.
