title: A weekly review in org-mode
body: <p>I'd like to generate an agenda view from org-mode which includes completed TODO items from the previous week. The following snippet seems like the prefered way to do it from reading the docs. However there are no items displayed in the agenda, only dates...</p>
  
  <pre><code>    (setq org-agenda-custom-commands 
        '(("W" "Completed and/or deferred tasks from previous week"
           ((agenda "" ((org-agenda-span 7)
                (org-agenda-start-day "-7d")
                (org-agenda-entry-types '(:timestamp :sexp))))))))
  </code></pre>
  
  <p>For example, the built in command <code>C-a-a</code> produces a list like this in the <code>*Org Agenda*</code> buffer</p>
  
  <pre><code>Week-agenda (W27):
  Monday      1 July 2013 W27
    gtd:        Scheduled:  DONE something important
  Tuesday     2 July 2013
  Wednesday   3 July 2013
  Thursday    4 July 2013
  Friday      5 July 2013
  Saturday    6 July 2013
  Sunday      7 July 2013
  </code></pre>
  
  <p>...but the custom command <code>C-a-W</code> as defined above produces this (despite various scheduled tasks during the period)</p>
  
  <pre><code>Week-agenda (W26):
  Monday     24 June 2013 W26
  Tuesday    25 June 2013
  Wednesday  26 June 2013
  Thursday   27 June 2013
  Friday     28 June 2013
  Saturday   29 June 2013
  Sunday     30 June 2013
  </code></pre>
  
  <p>Alternatively is there another way to generate a list of DONE items from the previous week?</p>
