New submission from Barry A. Warsaw:
Sometimes we want to control the order of arguments printed by an argparse defined cli. In practice, arguments are printed in the order in which they are added via add_argument(), but I don't think this is documented and thus should be considered an implementation detail. It should be possible to enforce an order by the use of a formatter_class, but you'd probably need some extra metadata on arguments to do this, so it's not completely obvious how to write such a formatter class.
Instead, I propose to document and officially support that the order of add_argument() calls defines the order in which arguments are printed via --help.
