(sorry for the resent, this time with minimal init.test.el)

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

I observe a strange interaction between whitespace-mode and org-mode
if org-ellipsis is set.

Whenever I use whitespace-toggle-options for customizing
whitespace-mode in a buffer, all org-mode buffers are effected.
Probably their display table is overwritten which only has effect if
org-ellipsis is set?

Steps to reproduce:

* Start emacs as follows (no local init file, start attached minimal
  init file, open two small org-files, also attached):

  $ emacs -q -l init.test.el test1.org test2.org

* Hit F10 in one org-mode buffer once.

* Look at other org-mode buffer to see that spaces are visualized via a
  centered dot.

What *is* happening:

* Other buffers are effected by a supposedly local action (display
  table?).

What *should* be happening:

* No change to other buffers should occur.

I'm not entirely convinced that org-mode is to blame here ...
