So far no one has suggested how this can be done.

Yes, but not immediately.
It's the same old problem: gnuplot mixes the input streams from the
keyboard and the current terminal into a single queue.  Thus both
terminal events and keyboard input are read via term->waitforinput().
If you change the terminal, you change the input routine and no longer
read events from the previous terminal.  

The events are not lost; they are delivered eventually when the terminal
is set back to the original type and term->waitforinput() is next called.

The problem for 'q' is slightly different.  Key bindings are handled
by gnuplot itself; the terminal drivers do not know about them.
So then the problem is how do you tell gnuplot_x11 that it should send
'q' as an event to the main program rather than exiting?

In the case of x11, gnuplot does not know this.
gnuplot_x11 reads it from an X resource.
