| In octave, this does not work, you need {'east' , 'west'} instead of {'east'

I checked in the following change.

Jaroslav, since this used to work in 3.0.x, I think this patch should
be applied to the 3.2.x release branch.

Debugging on error conditions is implemented, but someone needs to fix
the dbstop command to parse its arguments in a Matlab compatible way.
I'd certainly consider a patch.

For now, you can use

  debug_on_error (true);

instead.
