title: What does Fabric's `hide("everything")` actually hide?
body: <p>When I use the <code>hide("everything")</code> context manager, and a fabric task fails, I still get a message. The <a href="http://docs.fabfile.org/en/1.10/usage/output_controls.html" rel="nofollow">docs</a> read:</p>
  
  <blockquote>
    <p><strong>everything</strong>: Includes warnings, running, user and output (see above.) Thus, when turning off everything, you will only see a bare minimum of output (just status and debug if it’s on), along with your own print statements.</p>
  </blockquote>
  
  <p>But this is not strictly true, right? -- I see status, debug, and abort messages.</p>
  
  <p>If I really do want to hide everything, is there a better way than:</p>
  
  <pre><code>with hide("aborts"), hide("everything"):
      ...
  </code></pre>
