This proposal is essentially to require confirmation for lax completion.
With the `only-after-completion' value, confirmation would be required only
after TAB; any other non-nil value would always require confirmation for
input that doesn't match completely. Is that correct?

I have no objection to such an option to control the behavior, but I don't
think the default behavior should be changed.
