Hmmm, I see. It all depends on how you use you repository, I
guess. If you're doing something like:


where each of those second level subdirectories are
(non-branching-)tagged independently from the others, you're in
trouble.  When you create a new directory CVSROOT/gnu/grep, the
last thing you want is that to go under branch "2-05a" because
such happened to be the last version of bash you checked out.

Because this behaviour is "clearly wrong" in this situation, but
the alternative (do not create "Tag" files in parent directories)
would also be "clearly wrong" in other circumstances, would it be
crazy to add a command line option to checkout/update to control
which way it goes? Just checking, it doesn't hurt to ask... :)
