That's OK. Usually that works fine, and usually when there is a conflict I can
just fix it up. I'm not sure how I managed to drop that chunk, I'll have to go
back and look at what I did. I suspect I hand-edited the patch, and if you do
that wrong it can lead to patch just ignoring the rest of the patch.

I probably should have just asked you to rebase on my next, but given it was
already version 10 I didn't really feel like doing another revision :)
