The patch below adds a "forward" command to telnet, so that ticket
forwarding parameters can be modified after starting telnet and/or in
the .telnetrc file.
This patch was implemented by Marc Horowitz; I'm not claiming
authorship for it, just submitting it from OV's source tree so that it
can be integrated back into the MIT release :-).
