title: Shelves in Tortoise and Mercurial command line don't seem to interoperate?
body: <p>If I add something to a Mercurial shelf on the command line:</p>
  
  <pre><code>C:&gt; hg shelve ...
  </code></pre>
  
  <p>when I then look in TortoiseHG Workbench under the <em>Repository > Shelve ></em> menu, there is NO new corresponding entry (in the dropdown).</p>
  
  <p>Likewise, if I do the opposite and perform a shelving operation in THG, and then run <code>hg shelve -l</code> or just <code>hg unshelve</code> on the command line, it seems to ignore the new shelf.</p>
  
  <p>Why is this happening? Is there a setting or something like that which is affecting this?</p>
