I would use --nic here. --device/--netdev is covered by
docs/qdev-device-use.txt, which should be updated separately (it even
has -usbdevice still).

Same here.
Single vs. double-dash options is a confusing one and I'm not sure how
to proceed. On one hand single-dash is what everyone uses, on the other
double-dash is a bit more consistent with e.g. qemu-img. But:
1) the command-line of qemu-img is anyway completely different from QEMU's
2) mixing them is the worst of both worlds.
I honestly would use single-dashes, and add a note that double-dash
options are supported as well.
