title: svn: renaming feature branch in mid of development
body: <p>Have next situation:</p>
  
  <p>trunk branched at rev X -> branches/br1</p>
  
  <p>... dev with periodical synch trunk -> br1</p>
  
  <p>br1 renamed to br2 (at this moment br1 was not completely synched with trunk)</p>
  
  <p>... dev with periodical synch trunk -> br2</p>
  
  <p>finally br2 was synchronized with trunk. Try reintegrate from br2 to trunk, but TortoiseSVN show error like this:</p>
  
  <pre><code>Command: Reintegrate merge .../branches/br2 into ...wc\trunk
  Error: Reintegrate can only be used if revisions 12306 through 13012 were previously
  Error:  merged from .../trunk to the   
  Error:  reintegrate source, but this is not the case:   
  Error:   branches/br2/prj1   
  Error:     Missing ranges: /trunk/prj1:12359-12728
  Error:   branches/br2/prj2   
  Error:     Missing ranges: /trunk/prj2:12847   
  Completed!
  </code></pre>
  
  <p>Seems rename branch was bad idea :(</p>
  
  <p>So, how this situation can be resolved? Make reintegrate br1 and then br2? But currently br1 (deleted) not synchronyzed with trunk and far from it.</p>
