Bug#599941: /usr/bin/xset: xset dpms etc seems to operate on all screens rather than just those provided such as :0.1, in X zaphod mode

[Tim Connors <reportbug@rather.puzzling.org>]

Package: x11-xserver-utils
Version: 7.3+5
Severity: normal
File: /usr/bin/xset

My xorg.conf is set up to have dpms enabled on one screen (:0.1 -- I'm
using zaphod mode, so :0.0 is a separate screen to :0.1), but disable
on another screen (:0.0, a status screen that must always remain on).

This works, as is expected.  However, if I say:

DISPLAY=:0.1 xset dpms 1200 2400 3600

Then it affects :0.0 as well (even though xorg.conf says that screen
has DPMS disabled!).  It should only affect the asked for display.
Perhaps it should affect all displays if I was trying to talk to :0
rather than :0.0.

Those not using zaphod mode, but using xinerama mode instead,
obviously would have only the one DISPLAY, and thus xset should affect
them all.
