Ditto; no need for git here.

Rebase error?  It fails because this should be "git p4".

But then it fails here too because the code is indeed buggy. Nice to have this test too, to document the problem and maybe prod someone to fix it someday.

Do use "test_path_is_missing" for these non-existant file tests, though, please.
