title: Update-TFSWorkspace does not work
body: <p>Why does </p>
  
  <pre><code>Update-TfsWorkspace [[-Item] &lt;QualifiedItemSpec[]&gt;] [-All] [-Force] [-Overwrite] [-Recurse] [-Version &lt;String&gt;]
  </code></pre>
  
  <p>not work?
  The equivalent tf.exe works just fine in the exact same folder:</p>
  
  <pre><code>tf get itemspec [/version:versionspec] [/all] [/overwrite] [/force] [/preview] [/recursive] [/remap] [/noprompt]
  </code></pre>
  
  <p>Using Win 8.</p>
  
  <p>Here are the exact commands I'm using:</p>
  
  <pre><code>Update-TfsWorkspace -Item "$/myfilepaht" this does NOT WORK
  
  tf get itemspec "$/myfilepaht" #this WORKS
  </code></pre>
