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