octave-mode/SMIE question

[Eduard Wiebe]

 Hello,

i have a question about `octave-mode' and/or SMIE.

Consider the following snippet:

(define-derived-mode matlab-mode octave-mode "MATLAB"
  "My poor man's MATLAB mode based on `octave-mode'.
\\{matlab-mode-map}"
  (setq-local octave-end-keywords '("end")) ;; Without an effect
  (setq-local octave-comment-char ?\%)
  (setq-local octave-comment-start "%")
  (setq-local octave-block-offset 4)
  (setq-local octave-block-comment-start "%% "))

If matlab-mode is loaded and i use `smie-close-block' (C-c /), then
each block is closed with Octave-specific close token ('if' is closed
with 'endif', 'while' with 'endwhile' and so on).

But MATLAB-grammar knows only `end' as a block close token.

How i can accomplish the intended behaviour of `smie-close-block' for
my matlab-mode? Or is an advice my last chace?
