function.imap-search-description

The following example should highlight this bug clearly:
$newCount = count(imap_search($imap_stream, 'UNSEEN'));

We use the function above to count the number of 'UNSEEN' messages in the 
mailbox folders. It works fine until we have read all messages and in this case 
we would expect the $newCount to be 0. However it remains at 1!  We have been 
able to work around this bug with the following fix/function (see test script)



This returns the count as we would expect.  If you do address this bug we would 
appreciate a quick email and advise on the version of PHP it will be included 
in.

Many thanks.

Test script:
---------------
$newCount = $this->count_unread_email($imap_stream);

  function count_unread_email($imap_stream) {
      $count = 0;
      if (!$imap_stream) {
          echo "Error";
      } else {
          $headers = imap_headers($imap_stream);
          foreach ($headers as $mail) {
              $flags = substr($mail, 0, 4);
              $isunr = (strpos($flags, "U") !== false);
              if ($isunr)
              $count++;
          }
      }
      return $count;
  }

Expected result:
----------------
We expect the function to return 0 when there are no remaining 'UNSEEN' messages, 
not 1.

Actual result:
--------------
We receive a 1 even though there are 0 'UNSEEN' messages remaining in our mailbox 
folder.
