title: external diff tool meld not working with svn
body: <p>I have configured the following in the ~/.subversion/config to use the meld as difftool.
  by adding the following line 
  diff-cmd=svnmeld</p>
  
  <p>then added the following in the /usr/bin/svnmeld with executable path.</p>
  
  <pre><code>#!/bin/bash
  meld "$6" "$7"
  </code></pre>
  
  <p>But then i try to a diff on a file in the svn repo, i still donot see the meld being lauched.</p>
  
  <p>I am using the subversion, 1.8.5..</p>
  
  <p>Any idea, what might have gone wrong ?</p>
  
  <p>I have tried calling the meld directly, on command line like
  svn diff diff-cmd=meld file.cpp which works fine..</p>
  
  <p>thanks a lot</p>
