title: Differences between svn merge left, right & working files after conflicts
body: <p>When performing a 'svn merge' from my development team's trunk into a branch, we occasionally experience merge conflicts that produce files with suffix names: <code>*.merge-right.r5004</code>, <code>*.merge-left.r4521</code> and <code>*.working</code>.  I've searched throughout Subversions's documentation but their explanation hasn't been much use.  I've gathered the following:</p>
  
  <ul>
  <li>*.merge-right.r5004 = trunk version   </li>
  <li>*.merge-left.r4521  = ?  </li>
  <li>*.working           = branch version</li>
  </ul>
  
  <p>I can't seem to figure out what <code>merge-left.r4521</code> is.  And if the answer is that its simply an older version of the file from branch, then why 4521?</p>
