title: Visual Studio Code files.exclude setting not working
body: <p>I am using Unity and trying to exclude .meta files from the file explorer sidebar.  I navigated to File->Preferences->User Settings (or Workspace settings, doesn't matter), and set the contents of the file to the following:</p>
  
  <pre><code>// Place your settings in this file to overwrite default and user settings.
  {
          "files.exclude": {
          "**/.meta": true
      }
  }
  </code></pre>
  
  <p>...and saved my changes.  Yet, when I click the Refresh icon or close/reopen my folder view, I am still seeing all the .meta files showing up in the left pane.  Am I doing something wrong here?</p>
