title: Sass compiler says: Inconsistent indentation
body: <p>I have this in my main.sass:</p>
  
  <pre><code>#thing 
  {
         -moz-box-sizing:     border-box; 
      -webkit-box-sizing:     border-box; 
              box-sizing:     border-box;
  }
  </code></pre>
  
  <p>When compiling, sass says:</p>
  
  <pre><code>Inconsistent indentation: 7 spaces were used for indentation, 
  but the rest of the document was indented using 4 spaces.
  </code></pre>
  
  <p><strong>Is there a way to suppress this?</strong></p>
