Backport #7981: ruby does not respect --
https://bugs.ruby-lang.org/issues/7981

Author: mpapis (Michal Papis)
Status: Open
Priority: Low

Target version:


in `ruby --help` I have found:

    Usage: ruby [switches] [--] [programfile] [arguments]

so I have tried this example:

    $ echo 'puts :ok' | ruby -- --params
    > ruby: No such file or directory -- --params (LoadError)

I have assumed that `[argumments]` are independent from `[programfile]`

In the current state of code the help message should be:

    Usage: ruby [switches] [--] [programfile [arguments]]

But I would prefer that it would be fixed and anything after `[--]` that 
is not program gets ignored, so we can use the shell style:

    $ echo 'echo "args:$*:"' | bash -s -- --params
    > args:--params:
