Simplified a few argparse examples and fixed some incorrect documentation

I eliminated a few "narg=1" configurations so that a single str value is returned instead of a List[str].

I also reworded some documentation which was no longer correct after the last commit which made "history command" have the same help text as "command -h" when using one of the two argparse decorators.
