title: grunt replace all less files into css files
body: <p>I use grunt to convert all my less files into css files,using this:</p>
  
  <pre><code>less: {
    development: {
      files: {
        "css/*.css": "less/*.less"
      }
    }
  }
  </code></pre>
  
  <p>This worked on version 0.3.0, but now that I have upgraded to v0.4.0 it doesn't work anymore.</p>
  
  <p>The following code (not using * in the destination) works on both versions, so the problem is with the star on the destination file.</p>
  
  <pre><code>less: {
    development: {
      files: {
        "css/test.css": "less/*.less"
      }
    }
  }
  </code></pre>
  
  <p>Any idea ?</p>
