title: Limit length of characters in a regular expression
body: <p>Is there a way to limit a <a href="http://en.wikipedia.org/wiki/Regular_expression" rel="nofollow noreferrer">regular expression</a> to 100 characters <em>with</em> a regular expression?</p>
  <pre><code>\[size=(.*?)\](.*?)\[\/size]
  </code></pre>
  <p>So <code>Look at me!</code> wouldn't work.</p>
  <p>I want to limit the numbers, only allow numbers between 1 and 100.</p>
