[Orgmode] org-agenda-follow-link does not work with id links

[Matt Lundin]

When typing C-c C-o on an agenda id-style link, the cursor remains in
the agenda buffer and the link target is not displayed. I tested this by
placing the following tree in one of my agenda files:

--8<---------------cut here---------------start------------->8---
* Test
  :PROPERTIES:
  :CATEGORY: test
  :END:
** This is a test
   :PROPERTIES:
   :ID:       18381b26-2146-4a7c-aa4a-5a9e419cc174
   :END:
** [[id:18381b26-2146-4a7c-aa4a-5a9e419cc174][This is a test]]
   SCHEDULED: <2010-02-16 Tue>
--8<---------------cut here---------------end--------------->8---

This produces the agenda view below. When I type C-c C-o on the id link,
nothing happens.

--8<---------------cut here---------------start------------->8---
Day-agenda (W07):
Tuesday    16 February 2010
  test:       Scheduled:  [[id:18381b26-2146-4a7c-aa4a-5a9e419cc174][This is a 
test]]

Best,
