title: Add spaces within single line comment block in WebStorm
body: <p>When hitting <kbd>Ctrl + Shift + /</kbd> in CSS files, or in any files that only support comment block syntax, I would like WebStorm to add spaces within that block if it is on a single line, which is not the case by default. 
  I just can't find any options in CSS code style to achieve this.</p>
  
  <pre><code>My css comment
  </code></pre>
  
  <p><kbd>Ctrl + Shift + /</kbd> gives this :</p>
  
  <pre><code>/*My css comment*/
  </code></pre>
  
  <p>What do I want :</p>
  
  <pre><code>/* My css comment */
  </code></pre>
