Given that this series is somewhat small and has received two favorable
reviews I'd suggest that this can probably be merged down to "next".

I think this can be merged, too. Peff has positively reviewed the update
itself, the only change relative to that in v2 was to mark the self-test
files as being allowed to end in a blank line via gitattributes.

I somehow lost track of reviewing this topic. I've put it into my
backlog of stuff to review once I'm back in office (or when I find a
quiet minute where I'm bored).

There's a small set of nits I had on the final patch, but I don't really
think these necessarily need to be addressed. I'll leave it to Adrian to
decide whether or not he wants to do a final reroll.

I didn't find the time recently to focus on this topic. I think the
discussions mostly reached consensus though that we also want to adapt
these commands to rewrite dependent branches. I'll work this into the
series, but will probably only get to it in early January.

Thanks!
