Second take at retrieving the correct 'hanged()' value for the Fl_Input_Choice. Fl_Widget::changed() clears our flag where it should not, so we have to some trickery and set a second 'changed' flag that will not be cleared by Fl_Widget::do_callback. I did not see any side effects in doing this, but it is definetley a Kludge.
