[PLUG] given a display, find a host

[Jeff Abrahamson <jeff@purple.com>]

I have a program that knows that it's window is displayed on
$DISPLAY. It would really like to know what host it is displayed on. I
wonder if this is possible.

Before you suggest grabbing the part before the colon, note that this
is all through ssh, so DISPLAY typically equals something like
localhost:17.0.


In fact, this is happening in emacs, but a non-emacs solution can
still be made to work.
