I often use -W and the above would give us a natural extension, but
I agree that is a bit too dense and totally unintuitive.  As we use
parse-options for patch output formatting options, my pick would be
"--new-only" vs "--old-only" (if there were existing options that
has new/old in their names, "--preimage-only" and "--postimage-only"
would also work, but that's much longer), and let the option parser
accept unique abbreviations like "--new" and "--old".
