Thanks for the new testcase.  My previous fix to vertical-motion was
indeed too limited; I've checked in a more general fix.  Hopefully
preview-latex will work this time!

Hi,

if you start Emacs with `emacs -Q', execute the code included below
and type `C-n' several times, point will not move past the next to
last line.  This breaks cursor movement with preview-latex in some
cases.

Note that this is an updated test case.  A similar bug was fixed two or
three days ago.


(progn
  (pop-to-buffer "*foo*")
  (insert "xxx\nxxx\nxxx")
  (let ((ov (make-overlay 5 12)))
    (overlay-put ov 'before-string
		 (concat
		  (propertize
		   "A" 'display `(image :type xpm
					:file ,(concat data-directory
						       "images/attach.xpm")))
		  "\n")))
  (goto-char (point-min)))
