[Orgmode] Re: [PATCH] fix a bug in org-open-at-point

[Nicolas]

My bad, wrong manipulation. Here is the patch.

To reproduce the error, you can type the following in a fresh Org
#+begin_src org
target some text <<<target>>> another text target
#+end_src

Using C-c C-o on any of the two links will return an error.

Subject: [PATCH] Fix bug with link to radio target at beginning or end of buffer

* lisp/org.el (org-open-at-point): if a link to a radio target is the
  first, (resp. the last), element of a buffer, function cannot find
  the property change required to get its boundaries, and
  `buffer-substring' is called with an invalid nil argument.
