title: grunt globbing except a file
body: <p>I have a list of files:</p>
  
  <pre><code> 'app/scripts/module.js',
   'app/templates/templates.js',
   'app/scripts/**/*.js'
  </code></pre>
  
  <p>This will load <code>app/scripts/module.js</code>, <code>app/templates/templates.js</code> and then all the files under <code>app/scripts/**/*.js</code> except the one that was loaded before (module.js).<br>
  Now I want it to load another file located in <code>app/scripts/a.js</code> at the end of the list.<br>
  The problem is that when <code>app/scripts/**/*.js</code> is loaded, it already load <code>app/scripts/a.js</code>.<br>
  I want to write something like <code>app/scripts/**/*.js (!a.js)</code> - load all except a.js.<br>
  It this possible?</p>
