This didn't work for something like `pactl set-card-profile foo
<TAB>`,
because it didn't allow for the card name, as it would just print the
index again and again.
In such cases, `pacmd help` prints
No PulseAudio daemon running, or not running as session daemon.
to stderr, which ends up printed to the user terminal.
At least on Arch Linux, pacmd and pulseaudio aren't necessarily available just because pactl is (pipewire is now a thing, and it installs libpulse but not pulseaudio)
To implement this mostly as a wrapper around pactl, we add the list of
commands for this to that. It's 90% the same anyway. (This means that
`pactl suspend ` will complete files instead of commands like `pactl
banana ` would, but neither is correct)
