It's not clear how you would do this. If you can suggest a patch, I'd
be happy to consider it. However, and the moment, you get "-v" and
"--version" by simply specifying ArgumentParser(..., version="XXX").
So how do you deprecate just the "-v"?
All I can imagine you mean is to issue a deprecation warning whenever
a user of the script provides "-v" at the command line, but that seems
sketchy to me - we'd be deprecating features of someone's
*application*, not features of the argparse *library*.
