From: Jacob Keller <jacob.keller@xxxxxxxxx>
If a user renames the "origin" remote of a submodule, recursive fetching
can sometimes fail with an error similar to:
From git/git/t/trash directory.t5526-fetch-submodules/.
210db27..1fc7e77 super -> origin/super
Fetching submodule submodule
fatal: 'origin' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Errors during submodule fetch:
submodule
This occurs because of the way that recursive submodule fetch tries to
guess the remote name. It will fall back to the origin term even if that
remote doesn't exist.
Add a test which sets up this environment and shows the failure. The
problem only exists if there are multiple remotes, so add both a test
for a single remote and a test for multiple remotes which is marked as
test_expect_failure.
