bug in vertical-motion?

[Luc Teirlinck]

Do `emacs -q' and then hold the `q' (or your favorite letter) key down
until you get a continuation line.

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.

Sincerely,

Luc.
