Rereading my feedback and the parts of the v4 patch set that correspond
to my feedback, my comments (which were more about clarity anyway - I
didn't notice any correctness or performance issues) have been addressed
adequately. But to be fully sure, I would need to reread the patches to
ensure that nothing unexpected was introduced. :-P (If nobody does this,
I can do this - hopefully by the end of the week.)

I wonder if it would be worth splitting this branch into the first 15
patches (which I reviewed, and which has more of an algorithmic focus)
and the last 5 patches (which I didn't review, and which has more of an
integration-into-Git focus). That way, the last 5 wouldn't hold up the
first 15.
