In `org-fix-ellipsis-at-bol', the change wasn't
: (save-excursion (set-window-start (selected-window) (window-start)))

: (save-excursion (set-window-start (selected-window) (point-min)))

which is not a noop.

But it does the wrong thing with isearch.

When isearch is done, that is, when it has found a match and we leave
isearch with RET for example. Then it calls `isearch-done' which runs
`org-fix-ellipsis-at-bol' because it is in `isearch-mode-end-hook' (I
didn't look to find why).

Because of this, if the pattern found isn't at the top of the buffer,
then the point won't be at the pattern, but at the top of the buffer.
