experimental patch

DNS server may receive DNS queries related to tmux.
The following is an excerpt from my ISC BIND log.

19-Jul-2022 15:54:30.421 client @0x803584960 ::1#59707 (tmux\(67594\).%0): =
view
internal-in: query: tmux\(67594\).%0 IN A + (::1)
19-Jul-2022 15:54:30.421 client @0x803584960 ::1#60153 (tmux\(67594\).%0): =
view
internal-in: query: tmux\(67594\).%0 IN AAAA + (::1)

This query seems to be sent when a user whose login shell is tcsh/csh creat=
es a
new pane of tmux.
This is probably related to the function getremotehost in
/usr/src/contrib/tcsh/tc.func.c .

The patch is an experimental patch to stop this DNS query.
This patch misleads tcsh into thinking that tmux is an X server connecting =
to a
unix domain socket :)
