Indeed, this would save some network traffic, although you could also
specify the -z9 option to compress.  At the server side it wouldn't
matter very much, since cvspserver still needs to locally check out a
complete copy of the requested version, before it can send it to you.
(This is the reason that cvs checkout can sometimes take ages to start
actually pumping data. :)

If this kind of stuff is needed extremely often, it might be better to
simply rsync or cvsup the whole repository itself.  I'm not sure if
sources.redhat.com allows this, though...
