Me too, then. :) I think part of that copy is that we're moving the
items over to revs->commits, and dropping any non-commit objects.

Fair enough.

I suppose so.  I don't really have anything against the patch. My main
complaint was just that I don't think it's actually cleaning up the
gross parts of the interface. It's just substituting one gross thing (a
funny struct flag) for another (a special version of the prepare
function that takes a funny out-parameter).
