As I have nothing in the fixes-togreg branch, I've applied this to
the fixes-togreg-post-rc1 as that's the next one that will go upstream.
I don't tend to send Greg fixes during the merge window as he is
rather busy and won't pick them up until after anyways!
This may be delayed by a few weeks though as I'm travelling.
Thanks,
Jonathan
