I suspect that was me. "tweak" does means that the person doing the submit
to PQM can clean things up. If there's a chance the author may disagree with
the requested tweak or know a better way than I'm suggesting, I like to get
them involved again by asking them to do the tweak.

As far as this patch goes, the tests fail on Linux but it looks ok otherwise.
