title: Visual Studio Code: Git diff over git gutter indicator
body: <p>In <strong>WebStorm</strong> (and also <strong>Eclipse</strong>, <strong>Netbeans</strong>), when clicking on the <em>git</em> diff indicators in the gutter, a contextual menu shows the previous content, and provides a button to quickly revert the block modifications.</p>

  <p><strong>Visual Studio Code</strong> also provides added/modified/deleted blocks gutter indicators, this way:</p>

  <p>But I didn't find how to quickly see the corresponding diff. I can't believe there's no quick way to see what the gutter indicators refer to.</p>
  
  <p>Did I miss something? Is it an upcoming feature? Or would someone know about an extension that would add that behavior?</p>
