[Rd] X11 protocol errors after all x11 devices are closed (PR#1065)

[ripley@stats.ox.ac.uk]

> x11()
> dev.off()
null device
          1
> x11()
> plot.new()
Warning messages:
1: X11 protocol error: BadAccess (attempt to access private resource denied)
2: X11 protocol error: BadAccess (attempt to access private resource denied)

This only happens if all x11 devices are shut down, so the X11 connection
is restarted.  We had problems with this when the event handlers
were changed prior to 1.3.0, and it looks as if the logic is still
incorrect.

As far as I can see subsequent plots are correct.

Carrying on:

> dev.off()
null device
          1
> x11()
> plot.new()
Warning message:
X11 protocol error: BadAccess (attempt to access private resource denied)

(only one error this time).
