title: Prevent js-beautify from adding extra whitespace / empty lines
body: <p>js-beautify (used under VSCode) annoys me by putting extra lines after comments:</p>
  
  <p>My sample.scss</p>
  
  <pre><code>/* a fancy comment */
  .foo-bars {
      background: $gray;
      display: block;
  
      width: 26px !important;
  }
  </code></pre>
  
  <p>...becomes...</p>
  
  <pre><code>/* a fancy comment */
                        &lt;-- annoying empty line inserted
  .foo-bars {
      background: $gray;
      display: block;
                       &lt;--- (this is fine. I like it being preserved)
      width: 26px !important;
  }
  </code></pre>
  
  <p>This is my <code>.jsbeautifyrc</code> (verified to be effective, i.e. by testing with <code>"indent_char": "#"</code>)</p>
  
  <pre><code>{
      "indent_char": " ",
      "preserve_newlines": true,
      "max_preserve_newlines": 8,
      "keep-array-indentation": true,
      "break_chained_methods": false,
      "newline_between_rules": false,
      "selector_separator_newline": false,
      "end_with_newline": false
  }
  </code></pre>
  
  <p><em>update</em>: Affects <code>/* block comments */</code> only, not <code>// line comments</code>.</p>
