Should work without suddenly changing the default;  here are two interfaces
such that one may effect the other:


	Available network interfaces are: vio0 vio1 vlan0.
	Network interface to configure? (name, lladdr, '?', or 'done') [vio0] vio1
	IPv4 address for vio1? (or 'autoconf' or 'none') [autoconf] none
	IPv6 address for vio1? (or 'autoconf' or 'none') [autoconf] none

    New code worked, now requiring you to type an extra 'none' for IPv6 if you
    want to leave this accidentially entered leave unharmed...

	IPv6 address for vio0? (or 'autoconf' or 'none') [none]

Same if you enter 'vio0' twice:  the first round does not effect the second one.
^C out of the install and starting from scratch behaves equally, so I don't see
a problem here.

Then you're already against the defaults and need to enter (yet) another 'none',
tough luck.

It's impossible to make all those cases equally convenient and usually we go for
"just hitting [Enter] does the right thing", which this diff brings is one step
close to iff you deviated at just one point.
