Excellent! I am espicially impressed by the size of patch :-)

I even suggest, that this be included in distribution.

One problem. How should undo after this second widget behave? Curretly it
leaves the last match, selected in menu selection, inserted and forgets about
list. It would be very nice if it returned to menu selection ... but I do not
know how difficult it is.

More general. With amount of state information kept in compstate it is very
easy to write separate bindable commands that modify generated lists. It would
be very nice if undo returned to previous state in this case.
