Since the root of Timm's complaint was the non-deterministic return

print the no-such tag message when no files were checked out, only
when a tag was specified?

Just a thought.  I don't plan on doing the work myself just now.  I'll
need to see a patch before I consider this seriously.

Hmmm... I suppose that could be an approach. I would worry that a makefile
that does a 'cvs update -r foo -dP subdirectory' where no files were found
because subdirectory was intended to be pruned could be a problem case...

I think it would be better for CVS to provide a consistent return code. A user could always use `cvs up -dPrfoo subdirectory || true' or even parse the actual output of the command for the "no such tag" error message if they knew they'd like to ignore it.

Alternatively, I suppose we could start returning specific error codes on platforms which support return codes other than EXIT_SUCCESS & EXIT_FAILURE. Those might be more machine readable.

Again, I like these ideas but have no intention of implementing them myself anytime soon. I would, of course consider a patch.
