Re: [PATCH v13 5/9] remote set-head: better output for --auto

Since this particular test just wants to test what happens if
`refs_update_symref_extended` returns with 1 and not testing correct behaviour
of backends and such, would it be acceptable if this particular test case would
check for the backend and if it is reftables it will just pass without actually
checking and do the manually locking thing above for the files backend?

I think we have some pre-made test prerequisite to skip tests unless
run with a particular ref backend, exactly for that.  Perhaps

    test_expect_success REFFILES 'block update to check error' '
	... manually block update and see how the operation
	... errors out
    '

or something?
