The intention of the change I made is to make C-x ` go to the errors by
latest run-octave instead of past run-octave, i.e. one can M-x
run-octave multiple times in the same buffer. Is this useful?

I am not entirely sure but I have put in a call to
compilation-forget-errors in octave-send-region just like
prolog-old-process-file for example. Hope this makes sense.
