OK, here is a better test (courtesy of John Eaton):

mkfifo fifo1
then in one xterm:

gnuplot < fifo1

in another xterm:

cat > fifo1
set mouse
plot sin(x)
...

This works as expected on linux/x86, linux/ppc and is not working on MacOSX/X11...
(Tiger 10.4, kernel 8.2.0)

(BTW, the line in FAQ that one needs to set mouse in .octaverc is probably not
the best advice. I think it is better to set it in .gnuplot, this way if
gnuplot restarted in the middle of the octave session it still gets
mouse support.)
