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.
