I have added a check in gplt_x11 for the DestroyNotify event,
which should be generated any time a plot window is closed.
If it is the current plot window, then gnuplot_x11 passes the
information on to gnuplot via the mousing pipe using the existing
GE_reset mechanism.

On the gnuplot side I have added code to terminate the
paused_for_mouse state whenever a GE_reset event is seen.

Please let me know if this change resolves your problems with
running gnuplot via a script.  There are ways to close a window that
bypass this mechanism (killing gnuplot_x11 from the command line is
one of them), but I think this change handles the normal cases.
