title: Find deleted files in Mercurial repository history, quickly?
body: <p>You can use <code>hg grep</code>, but it searches the contents of all files.</p>
  <p>What if I just want to search the file names of deleted files to recover one?</p>
  <p>I tried <code>hg grep -I &lt;file-name-pattern&gt; &lt;pattern&gt;</code> but this seems to return no results.</p>
