title: Auto-Save fires `DocumentBeforeSave` event - How to circumvent this?
body: <p>When a file is saved (on purpose) I would like to perform a certain action.<br>
  This all works with the following code:<br>
  <code>Application.DocumentBeforeSave += new word.ApplicationEvents4_DocumentBeforeSaveEventHandler(ThisAddIn_BeforeSave);</code></p>
  
  <p>There is only one problem, this event also fires when a change is made to the document and the 'Autorecover' function saves this change.</p>
  
  <p>Is there a way to circumvent this action or at least detect if it was an auto-save?</p>
