+test_description='test git clone to cleanup after failure
+
+This test covers the fact that if git clone fails, it should remove
+the directory it created, to avoid the user having to manually
+remove the directory before attempting a clone again.
+
+Unless the directory already exists, in which case we clean up only what we
+wrote.
