I sort of tried to follow what was done in the rest of the file. If
this style is desired instead, I'll post an alternative series
instead.

Okay.

Redundant, as you pointed out in another email.

Ok. I don't like the `tail` thing. Why are you doing it instead of
comparing full outputs like the tests in the rest of the file?

Actually, we can't test this unless we actually create a branch with
20 commits and merge it. I've dropped this- you might like to add it
during the cleanup.

Okay.

I thought this was a bit of an overkill, so I removed it.

Okay.

Thanks! I found a bug and fixed it (patch will come in a moment).

Okay, sounds good.
