Change the test_create_repo code added in v1.2.2~6 to use a subshell
instead of keeping track of the old working directory and cd-ing back
when it's done.

Style: why not use
(
cd "$repo" ...
... .git/hooks-disabled
)
?

I've seen both used and I don't know which is preferred.

Okay. I maintain that the latter is way more readable. Is there any
advantage to the former?
Whichever the project chooses can be enshrined in
Documentation/CodingGuidelines, of course.

That is a sensible suggestion, but what does "error" do?
I think you would need || exit at the end, i.e.
(
... || error "..."
) || exit
or something.

Good catch, yes. error() calls exit so this patch as-is introduces a
logic error.
