Octave isn't aware of matlab's syntax. Last time I checked with octave's
mailing list, they didn't seem to like matlab's support in octave mode
anyway.

BTW, [UNTESTED] if you change octave-smie-bnf-table so that, for example:

         ("while" exp "end")
         ("while" exp "endwhile")

smie-close-block would pick "end" before "endwhile".
