Well it does usually take me a day or two push my local branch out,
however in this case I had actually dropped a ball somewhere.  I've
been through my backlog of 'applied' patches and these two are the
only ones I failed to pick.  I have now, re-picked, re-applied and
pushed the branch out.  Let me know if something is still not right.

Sorry for the inconvenience.
