Spec for "remaining args"

[rtpg]

It's pretty common for a wrapper script to consume some args, but to pass everything else down into some child script/binary/whatever.

my-wrapper-script --foo 1 --bar 2 -- --this-hits-the-underyling-script

I think it's worth having a mechanism to capture this pattern. Obviously with -- it's easy to make the split... there would be something neat in being able to outright do something similar to Python's argparse.parse_known_args so then you could capture "every part of argv that we didn't handle" but that's probably a bit heavier of a design decision

This is motivated by me wanting to use #/usr/bin/env -s usage bash but because so many of my scripts are wrapper scripts I want a nice way to capture remaining args here.

I'm a dumdum turns out I just wanted variadic args but misread what the feature was doing
