[O] org-special-ctrl-a/e no longer has the expected effect

[Matt Lundin]

Commit 8d2f0a441174c703ed0ed570e2f0eaf0da5d6aeb broke the expected
behavior org-beginning-of-line.

Steps to reproduce:

(setq org-special-ctrl-a/e '(nil . t)) ;; i.e., I want special
                                       ;; treament of the end of a
                                       ;; headline but not the
                                       ;; beginning 

* A headline
            ^ cursor initially here

Press C-a

Expected behavior:

* A headline
^ cursor moves here

Actual behavior:

* A headline
  ^ cursor moves here

This behavior is not what one would expect from the docstring of
org-special-ctrl-a/e.

Thanks,
