title: Compare files between two branches in TortoiseSVN
body: <p>I know how to do this in SVN,</p>
  
  <pre><code>svn diff http://svn.example.com/branches/A/File1.txt http://svn.example.com/branches/B/File1.txt
  </code></pre>
  
  <p>But there has to be a less painful way to do this in TortoiseSVN. You would think that you could do it from the Show Log, but it appears to only show revisions on the current branch.</p>
