argparse: allow abbreviation of sub commands by users

A patch was implemented, and then reverted when it was found to be buggy.

Subcommands are not parsed the same as long options.  Subcommands are actually 'choices' of a positional argument.  Trying to allow abbreviations of subcommands allowed them in all 'choices', resulting in backward compatibility problems.

I recommend using the suparser alias mechanism instead.

(I think this issue should be closed).
