Change its name to empty_dir_has_sparse_contents(), which more precisely describes its purpose. Reverse the return values, check_dir_in_index() return 0 for success and 1 for failure; reverse the values so empty_dir_has_sparse_contents() return 1 for success and 0 for failure. These values are more intuitive because 1 usually means "has" and 0 means "not found". Also modify the documentation to better align with the method's intent and behavior.
