4.3BSD and related systems (e.g. SunOS 4.0) normally have active ttys
owned by group "tty".  Xterm does not currently provide for this
convention.  The following patch adds the necessary functionality;
I hope the good people at MIT will look it over and include it in
the standard xterm if they so choose.
