No, the important thing is that we can detect somehow that multiport
virtio console is possible for some random version of qemu that we
have to work with.

The only feasible way we've been able to discover is to poke qemu with
various arguments (usually, "qemu -help") and then match on substrings
in the output.

If there's a better way to do this, please let me know.

But for now, having "(multiport)" there allows us to detect that
multiport virtio console is supported.

So is this documentation correct or not?
