title: Vundle plugin: Install concrete version of plugin
body: <p>I use vim and try the 'Vundle'. It helps to install plugins like in Ruby on Rails: </p>
  
  <pre><code>Bundle 'scrooloose/nerdtree'
  Bundle 'scrooloose/nerdcommenter'  
               ... I write in my _vimrc file
  </code></pre>
  
  <p>But when I do saw, it installs the last version of this plugins from github. But I want to install one of the previous version. Who knows how to do what I want?</p>
