missing "Usage:" in true/false

[sylvestre]

it should start with Usage:

Reported here:
https://bugs.launchpad.net/ubuntu/+source/rust-coreutils/+bug/2137580

$ LANG=C cargo run -q --features unix false --help|head -1
Returns false, an unsuccessful exit status.

with GNU:

LANG=C /usr/bin/false --help|head -1
Usage: /usr/bin/false [ignored command line arguments]

same for true

Hi,
Should the help output order template be modified globally in src/uucore/src/lib/lib.rs or should this ordering be applied only to true and false using a custom template?

[sylvestre]

let's start with true & false first
