Put cursor on the next to last `q' on the screen line that is
continued. Then M-: (vertical-motion 0) carries you to the beginning
of the current screen line, as one would expect. But then put cursor
on the very last `q' of the continued screen line. Then
M-: (vertical-motion 0) carries you to the beginning of the _next_
screen line. This appears to be a bug.
Do people get good results from this patch?
