[docs] [issue16697] argparse kwarg 'choices' documentation

[Brendan Barnwell]

Brendan Barnwell <brenbarn at brenbarn.net> added the comment:

This issue has sat idle for six years.  Meanwhile, the docs are still incorrect, giving every user wrong information about how the module works.  Can we consider just changing the documentation instead of worrying about what the behavior should be or what the rationale is?
