In Python 3.13 and 3.12.7, the behavior of _parse_optional has
changed. It used to raise an error on multiple matching actions
itself, and only ever return None or an option tuple. Now the
"raise error on multiple matching actions" code was moved out
into consume_optional, and _parse_optional returns either None
or a *list* of option tuples, which contains more than one if
multiple actions match. See:

python/cpython#124631
python/cpython#58573

This adapts to the change in a way that should work on both older
and newer Pythons. I re-implemented the handling of multiple
matching options so we don't have to worry about licensing and
attribution if we copied in upstream's version.
