Turns out this does not work for octave for some reason. default-directory
points to my home folder.

Also I'm getting "ansi-color-process-output: Marker does not point anywhere"
for Octave. So I have to C-c a couple of times on the block for the first
time. First evaluation just launches session but breaks because of that
error. Second time (when session is up) C-c works just fine and dumps
result. Non-session version of Octave works as expected. I wonder if it is
something Windows-specific... I can see test on :session for Octave and
Achim Gratz said it passed tests.

The problem occurs to me with git version of ob-octave.el as well. So I'm
confident it is not me who broke something during experiments :-)

Any idea? Matlab works just fine (session)!

I'm afraid I'll leave all the things as is for now. Maybe someone else can
fix it later.
