Ed Page c90a4eabae fix(help): Make output more dense
In looking at other help output, I noticed that they use two spaces, in
place of clap's 4, and it doesn't suffer from legibility.  If it
doesn't make the output worse, let's go ahead and make it as dense so we
fit more content on the screen.

This is a part of #4132

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,
```console
$ 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.
```console
$ busybox --install
? failed
...
```
Though users must pass something:
```console
$ 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 information
```
