[issue12713] argparse: allow abbreviation of sub commands by users

[Vinay Sajip]

Vinay Sajip <vinay_sajip at yahoo.co.uk> added the comment:

You could consider just a small refinement: in the first loop in _SubParsersAction.__call__ where you look for the abbreviation, you can just set parser_name = p and break. Then the logic just below that can stay as it is: all you've done is morphed the abbreviation to the full command name.
