-- style command only uses the first argument

I just tried it and I think it's implemented incorrectly:

% cargo watch -- cargo check
[Running 'cargo']
Rust's package manager

USAGE:
    cargo [+toolchain] [OPTIONS] [SUBCOMMAND]

OPTIONS:
    -V, --version                  Print version info and exit
        --list                     List installed commands
        --explain <CODE>           Run 
    -v, --verbose                  Use verbose output (-vv very verbose/build.rs output)
    -q, --quiet                    No output printed to stdout
        --color <WHEN>             Coloring: auto, always, never
        --frozen                   Require Cargo.lock and cache are up to date
        --locked                   Require Cargo.lock is up to date
        --offline                  Run without accessing the network
        --config <KEY=VALUE>...    Override a configuration value (unstable)
    -Z <FLAG>...                   Unstable (nightly-only) flags to Cargo, see 'cargo -Z help' for details
    -h, --help                     Prints help information

Some common cargo commands are (see all commands with --list):
    build, b    Compile the current package
    check, c    Analyze the current package and report errors, but don't build object files
    clean       Remove the target directory
    doc         Build this package's and its dependencies' documentation
    new         Create a new cargo package
    init        Create a new cargo package in an existing directory
    run, r      Run a binary or example of the local package
    test, t     Run the tests
    bench       Run the benchmarks
    update      Update dependencies listed in Cargo.lock
    search      Search registry for crates
    publish     Package and upload this package to the registry
    install     Install a Rust binary. Default location is $HOME/.cargo/bin
    uninstall   Uninstall a Rust binary

See 'cargo help <command>' for more information on a specific command.
[Finished running. Exit status: 0]
^C

It seems it's only using the first argument and passing it to , so there's no real difference to :)

 cargo watch -- 'cargo check'
[Running 'cargo check']
    Blocking waiting for file lock on build directory
^C
