These are *examples*, and I think it's good to give the users examples
for both ways of specifying a network connection. I'd really like to
avoid that people think that -nic is the only way of specifying such a
device, since you might not be able to configure all properties of the
NIC this way. On the other hand, -device + -netdev is really way more to
type, so we should also not only show this kind of examples. Thus a
mixture between both ways sounds like the right solution to me. But if
you disagree, let me know, then I can rework the patch again to either
only use -nic or only use -netdev in the examples.
