title: Revoking OAuth Access Token Results in 404 Not Found
body: <p>I'm working on an application that integrates with GitHub and am having issues "logging out" a user that was previously authenticated. When I attempt to revoke the authorization token for the user, I get a 404 Not Found response from the API.</p>
  
  <p>According to the <a href="http://developer.github.com/v3/oauth/#delete-an-authorization" rel="nofollow">documentation</a>, it looks like I should just be able to make a <code>DELETE</code> request to <code>https://api.github.com/authorizations/[authTokenId]</code>. I have tried a couple of different things including:</p>
  
  <ul>
  <li>Ensuring the Authorization header is set with the current auth token</li>
  <li>Ensuring the UserAgent header is set with what I use for the rest of the API calls</li>
  </ul>
  
  <p>Nothing seems to result in anything but a 404 though. I have validated that the token is valid and has that the Id matches with what is expected (<code>id</code> property from the authorization response and from the "check an authorization" response as well). Anyone have another thought on something I could be missing?</p>
