[docs] [issue13605] document argparse's nargs=REMAINDER

[Steven Bethard]

New submission from Steven Bethard <steven.bethard at gmail.com>:

There is an undocumented value for add_argument's nargs parameter, REMAINDER, which can be used to consume all the remaining arguments. This is commonly useful for command line utilities that dispatch to other command line utilities.

Though undocumented, it has been used successfully by at least a few different people:

http://code.google.com/p/argparse/issues/detail?id=52

And I just received an email from yet another user who used it successfully.

So I think it's time to graduate this from a hidden feature to a real documented one.
