title: svn - file in working copy seems "lost"
body: <p>I just managed to get into a weird situation with svn. One of my files seems 'lost' as far as the working copy is concerned. When I look on the server or do a fresh checkout of the containing folder in another location, the file is there, but in this one specific working copy it seems 'lost in space'. </p>
  
  <p>svn status reports no changes (so not even a missing file)</p>
  
  <p>svn update does nothing</p>
  
  <p>I even tried re-exporting the file to my working copy, to no effect.</p>
  
  <ul>
  <li>What is going on here?</li>
  <li>How can I fix the working copy? </li>
  </ul>
  
  <p>I would like to avoid having to resort to a fresh checkout of the whole working copy, if possible.</p>
