title: How to compare two revisions in Mercurial?
body: <p>I need to know what files have been added/modified/removed between two revisions. What I do:</p>
  
  <pre><code>hg status --rev 10:11
  </code></pre>
  
  <p>It looks okay. But when I have only one revision (initial = 0) it doesn't work.</p>
  
  <pre><code># not work
  hg status --rev 0:0
  # also not work as I want
  hg status --rev 0
  </code></pre>
  
  <p>There is no revision <code>-1</code>.</p>
