bug#14208: octave-mode bug in octave-help

[fulvio ciriaco]

Hallo,
this is emacs 23.4.1 as from debian wheezy:

GNU Emacs 23.4.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.10)
 of 2012-09-08 on trouble, modified by Debian

Reproducing?
emacs -Q
alt-x run-octave
C-c C-h
wrong type argument: commandp, octave-help

In lisp/progmodes/octave-mod.el I read:

(defun octave-help ()
  "Get help on Octave symbols from the Octave info files.
Look up symbol in the function, operator and variable indices of the info 
files."
  (let ((info-lookup-mode 'octave-mode))
    (call-interactively 'info-lookup-symbol)))

and find several references to octave-help within.
Fulvio
