[issue14364] Argparse incorrectly handles '--'

[R. David Murray]

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

It does look like there's anomalous behavior here of some sort, but I'd expect --test=-- to result in test="--", myself, rather than an error.  My intuition is that '--' would need to be preceded by a space to function as the 'end of options' marker.  Because of that, I've never tried the above scenario with a unix command, so maybe my intuition is wrong :)

Just for reference (the code paths may be different), there is another open issue about -- parsing, issue 13922.
