I'm not sure this is a bug, or simply a feature that annoys me. I'm
sorry if I picked the wrong mailing list.

When running the following
emacs -Q /tmp/foo.outline -f outline-mode -f end-of-buffer --eval '(forward-line -2)' -f hide-body

with /tmp/foo.outline containing:
,----
| * foo
| <a screenful of lines that do not start by a '*'>
| * bar
`----

My window then looks like:
,----
| ...
| * bar
`----
When I hit M-<, my window will look like:
,----
| * foo...
| * bar
`----

I would expect the screen to not go through the intermediate state with
an ellipsis at the beginning of the window.

If this is not a bug, what is a workaround ? The best I came up with is :

(let ((ws (window-start)))
  (save-excursion
    (goto-char ws)
    (skip-chars-backward "^\n")
    (while (and (not (bobp)) (invisible-p (1- (point))))
      (goto-char (previous-char-property-change (point)))
      (skip-chars-backward "^\n"))
    (redisplay)))

(the code to skip invisible text comes from move-beginning-of-line).

Thanks,

Hello,

TL;DR: Ping?

FWIW, this bug came from the Org mode ML, see
http://lists.gnu.org/archive/html/emacs-orgmode/2014-11/msg00795.html
but can be reproduced with outline-mode only (which is what I did in the
recipe).

I still don't have a good solution for this problem. My best idea is
something along the lines of

(defun fix-ellipsis ()
  (let ((ws (window-start)))
    (save-excursion
      (goto-char ws)
      (skip-chars-backward "^\n")
      (while (and (not (bobp)) (invisible-p (1- (point))))
        (goto-char (previous-char-property-change (point)))
        (skip-chars-backward "^\n"))
      (redisplay))))
(add-hook 'post-command-hook 'fix-ellipsis)

which is awful.

Does someone know if this is actually a bug or just me having weird
expectations ?

TIA,

--

It's not a bug, in the sense that the code does what it was supposed
to do in this situation.  IOW, no one coded any special treatment for
this situation, AFAIK.

I think it should become wishlist.
