Re: [PATCH 0/3] [RFC] tests: add test_todo() for known failures

> test_todo() is intended as a fine grained alternative to
> test_expect_failure(). Rather than marking the whole test as failing
> test_todo() is used to mark individual failing commands within a test. This
> approach to writing failing tests allows us to detect unexpected failures
> that are hidden by test_expect_failure().
