Hi Christophe,

Thanks for sharing the solution!  Here's something you might want to add
to it, something I recently discovered.  The `org-with-wide-buffer'
macro can replace those three lines:

#+BEGIN_SRC elisp
(defmacro org-with-wide-buffer (&rest body)
  "Execute body while temporarily widening the buffer."
  `(save-excursion
     (save-restriction
       (widen)
       ,@body)))
#+END_SRC

It's in `org-macs.el' so it's included with Org.
