How do I get the default Network Manager plus dnsmasq-base setup back again?

I finally found out what the problem was.  You have to remove *everything*
from /etc/network/interfaces except the loopback interface, otherwise
Network Manager assumes a manual configuration and does nothing.

So now my /etc/network/interfaces is:-

    # this file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).

    # The loopback network interface
    auto lo
    iface lo inet loopback

... and everything is working as it should!  :-)
