title: Mercurial marks unmodified files as modified in working directory and fails to revert
body: <p>Our team uses TortoisHg 2.0.5 on Windows and after refreshing file list in working directory it sometimes (at least once a day :(( ) shows a list of unmodified files as modified. Manual comparison doesn't show any changes in code, line breaks are also equal. Reverting of these "fantom" files causes no result. There a two way how we deal with this problem:</p>
  
  <ol>
  <li>Turning off eol extension and reverting the files,</li>
  <li>Manually removing the files and update them from the head revision.</li>
  </ol>
  
  <p>It's really annoying to do this every day (twice ...three times... per day), especially on large changeset! Please help to find a reason of the problem. </p>
