Expand description

Helper function for dealing with chains of ArgMatches while working in ActionCommand::action to find arguments which may have been specified anywhere in the subcommand tree.

// my-program --my-arg alpha my-subcommand --my-arg beta
let arg = get_raw(&matches, "my-arg");
assert_eq!(
    vec![OsStr::new("alpha"), OsStr::new("beta")],
    arg.collect::<Vec<_>>(),
);
