  Fix a few leaks `git_diff_get_patch()` would unconditionally load the patch object and then simply leak it if the user hadn't requested it. Short-circuit loading the object if the user doesn't want it. The rest of the plugs are simply calling the free functions of objects allocated during the tests.
