That's a problem with the GUI, not the parser.

As every module supports --o, the GUI should unconditionally add a
checkbox for overwrite. It shouldn't expect the parser to tell it to
do so.

The parser can't report --o etc as normal flags, because they aren't
normal flags; e.g. you can't combine them ("-x -y -z" can be
abbreviated to "-xyz", but that doesn't work with the "--" flags).
