title: maximum length of bit.ly generated url, "http" and everything included
body: <p>full explanation:</p>
  
  <p>I'm working on a project to generate twitter links that post over to twitter. My problem is twitter doesn't shorten the text correctly, and asks the user to fix the text. So I'm going to have javascript shorten the text to the maximum allowed without the extra being cut off by the user or twitter. </p>
