I tried coming up with a test in git-core that produces a remote similar to Gerrit, and let me tell you, it's not Git that is weird here. ;) >> > If $sha1 was not part of the default fetch ... fail ourselves here >> assumes that the fetch_in_submodule only fails when the serverside does > > I'm having some trouble with the formatting here.
