OK, it seems that (vertical-motion 0) is reliable now with your patch,  
but (vertical-motion 1) will sometimes move point to the beginning of  
the last word in the line (or so), possibly when the visual line is  
fairly long.  It looks as if it anticipates the word to be wrapped,  
even though it isn't.
