It took me a while to figure out what was causing the bug because you
didn't say precisely how to reproduce it.  My guess is that you see
this problem when you are typing comments that start with `%', but not
if they start with `#'.  If that is not the case, then please provide
a precise test case that I can use to reproduce the problem.

I think the following change is appropriate.  I don't know why `%'
would have been defined as punctuation instead of as a comment
starter, since it is not used in Octave for anything but starting
comments.

Thanks,

jwe

	* emacs/octave-mod.el (octave-mode-syntax-table):
	Make `%' a comment start character too.
