title: Bash set +x without it being printed
body: <p>Does anyone know if we can say <code>set +x</code> in bash without it being printed:</p>
  
  <pre><code>set -x
  command
  set +x
  </code></pre>
  
  <p>traces</p>
  
  <pre><code>+ command
  + set +x
  </code></pre>
  
  <p>but it should just print</p>
  
  <pre><code>+ command
  </code></pre>
  
  <p>Bash is Version 4.1.10(4). This is bugging me for some time now - output is cluttered with useless <code>set +x</code> lines, making the trace facility not as useful as it could be.</p>
