Aha, I think the problem might be that I left too much in when editing
the file; I have these lines:

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet static
address ....
....

as well as some auto wlan0, allow-hotplug wlan0 stuff, & same again
for wlan1, which I should delete.  I guess those come in the default
configuration for people using the USB wifi dongles instead of a
cable.
