Feature request: make two dashes end argument processing.

[coke]

➜  ~ rak -- -bak
The -- option (Option "foo" is False)
does not make sense in this context.  If you believe this to be incorrect,
please report an issue with https://github.com/lizmat/App-Rak/issues/new .
Option --a is called --dir with 'rak'.
Option --k is called --extensions=* with 'rak'.
Unexpected option: --b.
Specify --help for an overview of available options.

I expected this to search for the literal -bak, by having the two dashes (something keeps editing that into an endash here!) stop argument processing as it does on many common command line tools.
