As a statement of fact, there is nothing wrong per-se in this
message.  It may be an explanation why you should not run this as
root, but as an explanation of the reason why all tests in this
script are skipped, and more importantly, hint to testers what they
need to do to correct the situation, this is too cryptic to readers.

Perhaps telling them

	skip_all="do not run this test as root"

is more important and useful.

All of the above are positive tests.  One possible negative test is
to prepare a root-owned repository and see what "git status" as
yourself in there does.  And also see what "git status" as root
there does.

test_expect_success SUDO 'in root owned repository' '
	mkdir root/p
        sudo chown root root/p &&
	sudo git init root/p &&

	# owned by other person (root), do I see it as a repository?
	(
		cd root/p &&
		test_must_fail git status
	) &&

	# owned by root, can I access it under sudo?
	(
		cd root/p &&
		sudo git status
	)
