test_description='Test reading/writing .gitmodules when not in the working tree
This test verifies that, when .gitmodules is in the current branch but is not
in the working tree reading from it still works but writing to it does not.
The test setup uses a sparse checkout, however the same scenario can be set up
also by committing .gitmodules and then just removing it from the filesystem.
