I found some more 1-line hacks to nbdkit that can produce a subtly

I've now pushed this series as 32af175..b31e7ba
I'm still thinking about adding a strictness knob to let us decide
whether to try and cope with servers or fail as fast as possible on
the first non-compliance; but whether that belongs as a new bit to the
existing nbd_set_strict_mode (which to date has controlled client
strictness, not our response to the server) or a new API, is still
worth thinking about.
