Maybe the subject should rather be:
"submodule: document failures handling relative superproject origin URLs"

Nice test coverage!

But please use test_expect_failure for all tests that fail due to
current bugs and document what should succeed in the commands used
inside the test case (just like you did in v3). The only change
needed when the bug is fixed should be changing each
test_expect_failure to test_expect_success.
