Oh, I didn't realise that it hadn't been applied already, so I redid it
for the current trunk and tested it, and it seems to work as expected,
so I went ahead and pushed it.

Hm...  Well, I guess that's what most people would want...  but...
should it be user-controllable?  Perhaps read_minibuffer_restore_windows
shouldn't be a boolean, but allow values like t, 'completions and nil,
where 'completions would trigger this behaviour?
