It's because of pseudo-tty allocation. From "man ssh"
-T Disable pseudo-tty allocation.
-t Force pseudo-tty allocation. This can be used to execute arbi-
trary screen-based programs on a remote machine, which can be
very useful, e.g., when implementing menu services. Multiple -t
options force tty allocation, even if ssh has no local tty.
$ ssh -qt -l someone somehost somecommand
Will work. There doesn't appear to be any way to configure this on a
per-host basis in ~/.ssh/config though.
Will.
