old_upstream may be NULL at this point. I guess you want to skip this
line if old_upsteam is NULL.

The fact that I could find this bug suggests that this lacks a few new
tests too ;-).

For the 3 printf()s: we usually display commands without the "$", and
separate them from text with a blank line. See for example what "git
commit" says when you didn't provide authorship:

You can suppress this message by setting them explicitly:

    git config --global user.name "Your Name"
    git config --global user.email you@example.com

After doing this, you may fix the identity used for this commit with:

    git commit --amend --reset-author

(the absence of $ sign avoids the temptation to cut-and-paste it)

I've seen this style often, but sure.

Yeah, sorry. New laptop, hadn't got the default style fixed in the
config.

Done.

We've just set up tracking for it, so we'd want to undo that. Which
means --unset-upstream would have to move earlier in the series so we
can suggest that.
The fact that I could find this bug suggests that this lacks a few new
tests too ;-).
Indeed :) the next round will have them.

Yeah, I was going by what Junio wrote in his mail. We should probably
have a double-LF as well, like in the message below.
