bug#12785: [octave-mod] Changed behaviour of octave-mark-block?

[Mark Hepburn]

Hi all,

I'm wondering if the recent modernisation of octave-mod with emacs24 has

introduced an error; at least, it appears that the behaviour of

octave-mark-block is different.

For example, in the following trivial octave code:

for i=1:n, something; end;

If octave-mark-block is invoked with the cursor anywhere inside the

'for' token, it will fail ("unbalanced parentheses").  The following

situations all fail in the recent version, but succeed in the older

version: |for, f|or, fo|r.

Assuming this is in error I'm not sure how to fix it, I'm sorry.  The form

(and level (null (cadr level)))

seems a bit suspicious as there are no null entries in smie-grammar for

me, so that would be equivalent to just level.

It also looks like backward-up-list (-> up-list) might be incorrect for

similar cursor locations?  (Which may be the root cause I suppose)

Thank you for your time,

Mark.
