  Add unit tests for Commit parsing A few initial tests for commit parsing: "parse_buffer_test" tests git_commit__parse_buffer() with several malformed commit messages and a few corner cases which should pass. "parse_oid_test" tests git_commit__parse_oid() with several malformed commit lines containing broken SHA1 OIDs.
