Is this one necessary?  vshCommandOptString prints an error anyway
because the cpulist parameter is marked as required, ie:

  $ virsh vcpupin
  error: command 'vcpupin' requires <domain> option
  error: command 'vcpupin' requires <vcpu> option
  error: command 'vcpupin' requires <cpulist> option

+1

Again, vshCommandOptString prints an error:

  $ virsh attach-device
  error: command 'attach-device' requires <domain> option
  error: command 'attach-device' requires <file> option

And similarly.

Let me know if I'm missing something.
