Hmm, i wonder when they regressed that behaviour *again*. We've fixed
that in QEMU at least twice in the past. I'd like to see us explore
when this changed in QEMU and whehter we should fix it there instead.
I did some digging on this recently, see my findings here:
https://bugzilla.redhat.com/show_bug.cgi?id=1180092#c5
The issue is that there's two different monitor commands at play here, and the
set_password one we presently use has never had the semantics we advertise in
qemu.conf, so I'm guessing something like Jiri's patch will be needed regardless
