title: Why does "git difftool" not open the tool directly?
body: <p>I configured <code>git</code> like this:</p>
  
  <pre><code>git config --global diff.tool meld
  </code></pre>
  
  <p>When I run: </p>
  
  <pre><code>git difftool
  </code></pre>
  
  <p>I get the following message:</p>
  
  <pre><code>Viewing: 'hello.txt'
  Hit return to launch 'meld': 
  </code></pre>
  
  <p>Then, if I press <kbd>Enter</kbd>, <code>meld</code> will launch.</p>
  
  <p>How can I disable this message, so that <code>meld</code> will be launched straight away after typing <code>git difftool</code>?</p>
