bug#7080: 23.2; In octave-mode of emacs, fltk based figure window does not close

[Daisuke TAKAGO]

hello,
I noticed that in octave-mode of emacs, figure window generated by
fltk-backended octave does not close. Nothing happens, while I click [X] button
on the figure window. When I use octave on a normal terminal(rxvt,for
example), it works well(I can close the windows correctly).

The gnuplot-backended octave works well on octave-mode of emacs and on
normal termninal. GNU Octave version is 3.3.52.
