title: How well "hg mv" command performs
body: <p>Let's say, there is <code>file.txt</code> in a repo and two people are hacking it. One of them moved <code>file.txt</code> to another folder with <code>hg mv</code> and immediately pushed this into the repo. Is there any chance that Mercurial will automatically merge changes from original <code>file.txt</code> into the moved <code>file.txt</code> when the colleague decides to push its own touch ups?</p>
  
  <p>Am I too optimistic?</p>
