[issue15847] parse_args stopped accepting tuples

[Steven Bethard]

Steven Bethard added the comment:

The fix looks about right to me.

There's a bug in the tests though:

    parser.parse_args(('x'))

should probably be:

    parser.parse_args(('x',))

since I assume the intent was to test tuples.
