ArgumentParser.add_subparsers() argument spec discrepancies

[MatthiasHeinz]

Documentation

The function-signature currently reads ArgumentParser.add_subparsers([title][, description][, prog][, parser_class][, action][, option_string][, dest][, required][, help][, metavar]), but when trying to use the parameter option_string, the error-message suggests, that this parameter does not exist. On the other hand, the code does suggest a parameter called option_strings (with an additional 's' at the end).

Please update the docs accordingly.
