Subject: [PATCH] Fix detect defaults when nargs present

If a plugin adds a command line argument with the `nargs` parameter, e.g. `nargs='+'`, this parameter gets filtered from the `HelpfulArgumentParser` created/used in default detection. As a result, this parser does not parse the command line in the expected way, instead using the default value for `nargs`.

Leaving `nargs` in place resolves this issue.
