title: rewrite rule match all or nothing
body: <p>I can't handle one <code>ReweriteRule</code></p>
  
  <pre><code>RewriteRule ^thingsy_things_(.*)(_in_)?.*?/?$ /$1 [NC,L]
  </code></pre>
  
  <p><strong>URL:</strong> <code>www.mydomain.com/thingsy_things_name_name_in_somewhere/</code></p>
  
  <p>but sometimes it could be: <code>www.mydomain.com/thingsy_things_name_name/</code></p>
  
  <p>That name part could be <code>name_name_name</code> or more.</p>
  
  <p>Perfect delimiter is <em>in</em> but in case of <code>(_in_)?</code> rule matches everything in first group. </p>
  
  <p>How to handle that?</p>
  
  <p>Thanks!</p>
