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 :-).

State-Changed-By: hartmans
State-Changed-When: Fri Nov 1 20:49:09 1996
State-Changed-Why:
Implemented. In addition to applying the patch, I moved some #defines
from kerberos5.c to auth.h in libtelnet so things would work. This
was reasonable because the #defines were already duplicated between
main.c and kerberos5.c, and more duplicate code sucks.
