title: gitignoring a particular folder
body: <p>I am trying to use a .gitignore file to ignore a top level /assets directory, so my file says:</p>
  
  <p>assets/</p>
  
  <p>This is working - however other folders at lower levels of my app are also getting ignores - any folder called assets is being ignored.  eg. /style/img/assets.  </p>
  
  <p>So how to I specify I only want the /assets directory at the top level to be ignored?</p>
