Details:

emacs does not recognize the "end" keyword as a block delimiter in
octave-mode. Upon inspecting the file octave-mod.el, I see the following line
before the variable "octave-end-keywords":

";; FIXME: only use specific "end" tokens here to avoid confusion when "end"
;; is used in indexing (the real fix is much more complex)."

I could not ascertain what the fix was, but I tried manually appending the
"end" keyword in the "octave-end-keywords" list as well as the
"octave-block-match-alist" environment, and I could not get the "end" keyword
to be recognized. I did not understand why this was so because upon doing a
find for "endif" on the file, one sees that "endif" occurs exactly thrice -
once for a short-cut, and once each in the above-mentioned environments, and
putting the "end" keyword on the same footing as "endif" would be naively
expected to work (also "endwhile" and "endfor"). I have the following in the
my .emacs file:

;; octave bindings

(autoload 'octave-mode "octave-mod" nil t)
(setq auto-mode-alist
      (cons '("\\.m$" . octave-mode) auto-mode-alist))

(add-hook 'octave-mode-hook
          (lambda ()
            (abbrev-mode 1)
            (auto-fill-mode 1)
            (if (eq window-system 'x)
                (font-lock-mode 1))))

(defun RET-behaves-as-LFD ()
  (let ((x (key-binding "\C-j")))
    (local-set-key "\C-m" x)))
(add-hook 'octave-mode-hook 'RET-behaves-as-LFD)

(setq octave-auto-indent t)



Specifically, I want the "end" keyword to indent properly because I have to
write matlab-compatible code - the University server I submit jobs on has
matlab installed on it and the sysadmin is reluctant to install octave there.

I have noticed an older version of octave-mod.el on the website:

opensource.apple.com/source/emacs/emacs-41/emacs/lisp/progmodes/octave-mod.el

which I am also attaching here, in which the "end" keyword is explicitly
present in the octave-end-keywords list. Substituting this file for mine own,
however, did not work for me.
