title: glob for all folders within a folder except one named folder
body: <p>I am writing my Karma conf based on</p>
  
  <p><a href="http://karma-runner.github.io/1.0/config/preprocessors.html" rel="noreferrer">http://karma-runner.github.io/1.0/config/preprocessors.html</a></p>
  
  <p>The key for the preprocessor is a glob string.</p>
  
  <p>This works for all folders within the build folder:</p>
  
  <pre><code>build/**/!(*.spec|*.bundle|*.min).js
  </code></pre>
  
  <p>However, I don't want all folders. I wanted folder 1,2,4,5 NOT folder 3</p>
  
  <p>Can I write that in a single string (as seems to be required by karma)?</p>
  
  <p>Something like </p>
  
  <pre><code>build/(folder1|folder2|folder4|folder5)/!(*.spec|*.bundle|*.min).js
  </code></pre>
  
  <p>or even better</p>
  
  <pre><code>build/** but not folder 3/!(*.spec|*.bundle|*.min).js
  </code></pre>
