title: JSHint: Overwrite single .jshintrc option for whole folder
body: <p>I have a <code>.jshintrc</code> at the root of my project with the following configuration:</p>
  
  <pre><code>{
    "node": true,
    "smarttabs": true,
    "undef": true,
    "unused": true
  }
  </code></pre>
  
  <p>This is fine for all the node related stuff I have in the project, but not for the browser related scripts. Which are sitting in a subfolder.<br>
  Is it possible overwrite just the <code>node</code> option while preserving the other options for a whole folder?  </p>
  
  <p>If I create another <code>.jshintrc</code> file for the browser side folder I have to tell JSHint again about all my configurations, although I actually just want to unset the <code>node</code> option.</p>
  
  <p>I know that I can set this option in every file but I actually would like to avoid that.</p>
  
  <p>Many thanks in advance!</p>
