title: Output replacement summary in ant replaceregexp task
body: <p>Is there a <code>summary="true"</code> equivalent in ant <code>replaceregexp</code> tasks like there is in the simple ant <code>replace</code> task?  </p>
  
  <p>Here's my use case.  I am replacing an ant replace task with a replaceregexp task, like so:</p>
  
  <pre><code>&lt;replace dir="${dir}" summary="true" value="" token="Some Text"&gt;
      &lt;include name="**/*.jsp" /&gt;
  &lt;/replace&gt;
  </code></pre>
  
  <p>Becomes this:</p>
  
  <pre><code>&lt;replaceregexp byline="true"&gt;
      &lt;regexp pattern="Some\s*Text"/&gt;
      &lt;substitution expression=""/&gt;
   &lt;fileset dir="${dir}" includes="**/*.jsp"/&gt;
  &lt;/replaceregexp&gt;
  </code></pre>
  
  <p>However, I cannot find a way to have my ant build output the number of replacements which have been made.  There is no <code>summary</code> attribute for <code>replaceregexp</code>, and the documentation does not offer any ready suggestions.  Is this possible?</p>
