[issue10424] better error message from argparse when positionals missing

[R. David Murray]

R. David Murray <rdmurray at bitdance.com> added the comment:

I would remove the docstring from the new test class...if more tests of message content are added that docstring won't be accurate.  It really isn't needed.  (Also, shouldn't the test method be named test_missingarguments?)

I would also like to see a test where there are optional non-option arguments (nargs='?'), where you test that the optional one does *not* appear in the message.  That'll give you a second test method, making that test class a *little* less trivial :)
