Thank you so much for the patch! I've uploaded it with minor
modifications to xenial. Specifically, adjusted changelog (version
simplification, wily->xenial, named patch file) and ran update-
maintainer.

The attachment "debdiff" seems to be a debdiff. The ubuntu-sponsors
team has been subscribed to the bug report so that they can review and
hopefully sponsor the debdiff. If the attachment isn't a patch, please
remove the "patch" flag from the attachment, remove the "patch" tag, and
if you are member of the ~ubuntu-sponsors, unsubscribe the team.
