This interface is a lot simpler to explain and use than the one in my patch,
and more in tune with the rest of the C API.
I had a minor documentation suggestion which I put on the tracker item, but
other than that +1 on using Travis's patch instead of mine (I've already
rejected my own tracker item).
Cheers,
Nick.
