flatten doesn't work without expand

[jenrik]

Enabling flatten does nothing when expand is disabled Tested with the following settings

{
  copy: {
    css: {
      expand: false,
      flatten: true,
      src: [
        'bower_components/normalize-css/normalize.css'
      ],
      dest: 'source/css/vendor/'
    }
  }
}

Glad to see this issue is getting some attention, having the same problem myself...

This happens to me as well

Nowhere is it explained what 'expand' does. Every example has expand: true. What does expand mean?
