next-line + newline-in-fringe + outline-minor-mode

[Stefan Monnier]

   > emacs -q lisp/smerge-mode
   M-x outline-minor-mode
   C-s -funct C-a
   C-n

when I do the above, the `-funct' text is on a line of exactly 80 chars and
when I do C-n Emacs skips two lines instead of just one.
The outline-minor-mode is only relevant in that it turns on
line-move-ignore-invisible.  I.e. the following shows the same problem:

   > emacs -q --no-site-file
   C-u 80 a
   RET RET
   C-p C-p
   M-: (setq line-move-ignore-invisible t)
   C-n
