While this should be fixed, it's certainly not a show-stopper if it's just a user-to-user annoyance. Nobody sensible runs send-pr as root. So, assuming I'm right about the urgency involved, have you investigated the possibility of a patch from the vendor? Although the send-pr.sh file isn't on the vendor branch any more, it'd make sense to try to use a vendor-supplied patch. Ciao, Sheldon.
