urgh, this was a rebase gone wrong and I had been staring at the patches for
too long to see anything. and that hunk above clearly belongs into the other
patch (4/8).
regarding const: we don't have const in a whole bunch of places. I started
adding it yesterday but didn't finish down that road. Constifying the API
will be a separate commit.
