This is an intermediate solution for #4408. As there were no agreeed upon goals, I went with what I felt read well and that I saw commonly used on non-clap commands. - "information" isn't really a necessary word. - I originally favored `Print this help` but realied that doesn't read correctly in completions. - Besides being shorter, the reason for the flipped short/long hint is it gives people the context they need for scanning, emphasizing "summary" and "more". Fixes #4409

See the documentation for [Command::multicall][crate::Command::multicall] for rationale.
This example omits every command except true and false, which are the most trivial to implement,
$ busybox true
? 0
$ busybox false
? 1
Note: without the links setup, we can't demonstrate the multicall behavior
But includes the --install option as an example of why it can be useful
for the main program to take arguments that aren't applet subcommands.
$ busybox --install
? failed
...
Though users must pass something:
$ busybox
? failed
Usage: busybox [OPTIONS] [APPLET]
APPLETS:
true does nothing successfully
false does nothing unsuccessfully
help Print this message or the help of the given subcommand(s)
Options:
--install <install> Install hardlinks for all subcommands in path
-h, --help Print help
