Is getting back to the initial state important?  Just toggling correctly
seems more important, as long as the menu entry is a toggle.  From the
user point of view there are 2 visible states: lines are / are not
truncated.  The fact that emacs has more complexity than that underneath
is just an unfortunate detail... (Obviously this is all IMO)
