This has become less generic.

Likewise.

They used to be usable in any test repository, but now they have to
be used in a repository whose name is "test".

I wonder if something like

	check_foo () {
		if test "$1" = -C
		then
			in_repo=$2
			shift 2
		else
			in_repo=
		fi &&
		actual=$(git ${in_repo:+-C "$in_repo"} subcmd ...) &&
		do things ... &&
		do more things
	}

would work better?

Clear improvement.

This is a clear improvement.

These two are a bit questionable (it hides the fact that all these
names refer to stuff in "test" subdirectory).
