The example I had found below the new ones used --git-dir, but yeah, there's no
reason not to use -C instead. Changing.

Done, didn't know about it and it's not used in the test I referred to
while writing this one ('push --all can push to empty repo'). Thanks, I
learned something new.

I'm not sure I would say "more succinct." This leaves the test with the
same number of lines, but now it says:
Make some commits
Name a Git directory
Clone to the new Git directory
Do some config on the new Git directory
Name a remote URL
Change some commits
...
In my opinion, it's more readable the way it is now:
{Do some setup stuff.}
Name a Git directory
Init it
Config it
Name the remote URL
{Do the test stuff.}
Make some commits
Push some commits
Change some commits
...
I did add another comment to separate "Make 'up'" and "Make up/master",
which I hope expresses my intent in organizing it this way.

Sure, changed.

(Junio replied to this downthread... I have more to ask too.)

Oops, I thought I had omitted the new braces when I was staging the changes.
Really sorry for the distraction. You're right that it makes the diff
look weird.
