New submission from Bob Alexander <bobja...@gmail.com>:
This program:
import argparse
ap = argparse.ArgumentParser()
ap.add_argument("arg", nargs="*")
ap.parse_args()
Gives usage message:
usage: help_complexity.py [-h] [arg [arg ...]]
It's correct, but unnecessarily complex and challenging to the user.
If I were manually writing the usage, arg... would do, or maybe [arg ...] to be
consistent with other messages??
