Research direction

Start with the attached reproduction files bug_argparse.py and test.py, then inspect argparse's handling of REMAINDER. Use issue14174_1.patch to understand the previously proposed direction and reproduce the reported parsing behavior. Done means the remainder is parsed as expected by the reproduction cases and the behavior is covered by a regression test.
