[issue44208] argparse: Accept option without needing to distinguish "-" from "_" in arg_string

[Catherine Devlin]

Your PR doesn't include any tests... but I like the idea enough to create the tests for you if you prefer.

However, first I'd like to see whether the core devs like the idea.  I could see saying either "yes, why not make things easy" or "no, there should be only one way to do it".
