title: Re.match() returns always none
body: <p>I feel kind of stupid but it does not work:</p>
  
  <pre><code>import re
  
  a = " ebrj wjrbw erjwek wekjb rjERJK ABB RAEJKE BWE RWEJBEWJ B KREWBJ BWERBJ32J3B23B J BJ235JK BJJ523 2"
  
  print re.match(ur'/(wekjb|ABB)/',a)
  if re.match(ur'/(wekjb|ABB)/',a):
      print 'success'
  </code></pre>
  
  <p>I have the <code>ur'</code> if the user given <code>a</code> is unicode. I want to print success if <code>wekjb</code> or <code>ABB</code> is in the string but I always get <code>None</code> as the result of the <code>match</code>.</p>
