unexpected "replot" in "pause mouse"

[Petr M. <mi...@ph...>]

When using "mouse pause" in Octave together with the "ginput.m" routine
which waits for mouse clicks, I've noticed gnuplot redraws the plot after
each click.
I want to get rid of this -- mouse is not changing anything on the
plot, thus redraw is not necessary.

The reason is in mouse.c:

 /* Terminate via replot if we are in 'pause mouse' */
 /* FIXME EAM: untested for mouse devices other than X11 */
 if (paused_for_mouse) {
    paused_for_mouse = FALSE;
    do_string("replot");
    fputc('\n', stderr);
 }

It works fine with the "replot" being removed; however, under X11:
- running
	gnuplot> pause mouse
  does not return to the prompt "gnuplot> " afterwards

- In Octave, I have to write
	graw('pause mouse\n\n');
  instead of
	graw('pause mouse\n');
  otherwise first character from the next command is eaten.

Maybe both have the same reason?

The "replot" should go away, as it is an unexpected feature.
