Details:

This is a small fix to the behavior of the octfile implementation of the
signed mod function.

Currently the function returns y if x%y==0 and y<0. Example: x=-125, y=-25
will return -25 instead of 0. The patch changes behavior to return 0.

I've included a few files to show the current behavior and how it differs from
MATLAB.
