[O] Export options processed in example block

[Nicolas Quiniou]

Hi,

When I put #+TITLE in a block example and try to export an Org file in
HTML (with org-export), results are unexpected :

Org file
--
#+TITLE: Testing example block
#+begin_example
#+TITLE: My title
#+end_example

HTML file
--
[..]
<title>My title</title>
[..]

To obtain expected results, I found two solutions :
- prefix "#+TITLE: My title" with ';'
- put "#+TITLE: Testing example block" *after* "#+TITLE: My title"

To my mind, example is a protecting-block. Therefore, as mentionned in
org-protecting-blocks documentation, his content should not be
"processed as Org syntax".

Regards,
