title: fabric.api.run converts stderr to stdout for SSH
body: <p>I run compilation on serve using fabric, server is Linux and client is Windows, channel is SSH.</p>
  
  <ol>
  <li>On server 'scons' prints compilation errors to stderr. It is okay.</li>
  <li>But fabric.api.run('scons') executed from client prints compilation errors to STDOUT. It is not good and because of this my IDE fails to detect them.</li>
  </ol>
