make help subcommand order last (first)

[RustyJoeM]

Hello,

is it possible to make the built-in help subcommand in the help output on the last (or first, worst case?) position, other than setting e.g. display_order(1) to all the declared sub-commands (works, but feels a bit cumbersome)?

(I tried to search through method's docs, but keywords like order/last/help etc. are a bit too generic to narrow down on potential setting)

my-cli$ help
    <SUBCOMMAND>

SUBCOMMANDS:
    dump    ...
    help    Print this message or the help of the given subcommand(s)
    send    ...
my-cli$ help

You have two routes for resolving this

1. Add #[clap(setting = clap::AppSettings::DeriveDisplayOrder)] to your Parser and all commands will be in the order you define them rather than sorted. help will be last
2. Add a Help command and set its display_order. Since auto help hasn't been disabled, we will still apply the default help policy to this command, you are just overriding the UX of it

perfect, thank you for directions!

Note that in clap v4 we expect to make DeriveDisplayOrder the default / only option and people will have to go through extra steps to sort. See #2808
