title: Strange "local" folder inside virtualenv folder
body: <p>After I create my virtualenv environment (VE), inside it there is a symbolic link named "local". It points to the VE folder, which means that if you open it you end up in the same folder that you started in.</p>
  
  <p>I wouldn't care about that, but it makes some autocompletion "wizards" in PyCharm unusable (they show the same item over and over again, each time with a deeper nesting level).</p>
  
  <p>Somehow I cannot find any hint about this problem (I'm using virtualenv 1.6.4). </p>
  
  <p>The question is: what's that "local" symlink used for ?</p>
