bug#18324: plots hang in inferior octave mode

[Rüdiger Sonderfeld]

Please try the latest octave-mode from Emacs trunk 
http://bzr.savannah.gnu.org/lh/emacs/trunk/annotate/head:/lisp/progmodes/octave.el

It has been significantly improved and should include changes for GNU Octave 
3.8.  It should also be backwards compatible to GNU Emacs 24.3.

Regards,
Rüdiger
