Currently, when django is doing url matching, and it reaches a point where the urls.py file is including another urls.py, it will discard the part that was mathced so far, and then begin matching inside the included urls.py. This patch will enable passing that discarded part (here called stem) to the view that will be eventually called.
This will be useful in the case where one view is called by many url patterns from many urls.py files. It will enable the view to know where it was called from.
This patch is fully backwards compatible.
