[That would be only `setopt LIST_AMBIGUOUS'.]

After playing with bash a bit, it seems that to fully copy the
behaviour one would have to setopt LIST_AMBIGUOUS and use something
like:

  lastbuffer=''  # non-local variable definition

  ...

  completion-widget() {
    ...
    [[ "$BUFFER" = "$lastbuffer" && "$WIDGET" != "$LASTWIDGET" ]] && return
    ...
  }

At least I get completion of the unambiguous stuff on the first tab,
nothing on the second and the list on the third.

See above. Also: to allow the completion widget to say if only
something should be inserted or if also the list should be shown, we
would need a way to control this kind of stuff from the widget. This
is on my wish list (it also appears somewhere in my longish
description mail), but not yet implemented.
