Thanks. For the future, though, merge fixes like this should be part of the actual merge commit to avoid bisection problems.

I flip flop on this one, between retaining your contribution explicitly and merging them in. Usually I squash them in, but this felt substantial enough to retain explicitly. Worst case if someone is unlucky they need to git bisect skip once. I guess next time I should do a topic branch, apply it there on top of the pull, and then pull that in so that it's both pretty history and no bisect hole. -Daniel
