This plan is completely bogus.  Why is it choosing to write to the
output file?

I think what's happened here is that when I rewrote the planner
it has exposed a latent bug.

It should be dropping any plan which involves running virt-resize on a
same-named file, since that is impossible.  Probably adjusting the
weights caused that plan to become the best one, exposing the
(existing) bug.

I'll have to think about this one ...
