Comments in emacs

[Olivier Lefevre]

I am editing m files in emacs, in the Octave mode. Whenever
After I start a comment line with a %, the moment I insert
a blank space emacs insists on positioning the % at col 32!
This is extremely annoying behaviour and a strong disincentive
to writing comments. Would anyone know how to make that stop?
I had a look at octave-mod.el but nothing struck me.

Thanks,
