HTML code in subject en body

Example subject:
[<em>Subject (email)</em> - <em>E-mail</em>] <em>terst</em>

Example first part of the mail body:
<em>admin</em> sent a message using the contact form at
<em>http://www.domein.test/drupal5/email/13/field_email</em>

This can be repaired by replacing the % symbols by @ symbols. This prevents theming the replaced parts with the default emphasized tag.

Line 353 becomes:

  $message[] = t("@name sent a message using the contact form at @form.", array('@name' => $edit['name'], '@form' => url($_GET['q'], NULL, NULL, TRUE)));

Line 362 becomes:

  $subject = t('[@title - @contact] @subject', array('@title' => preg_replace("/\r|\n/",'',$node->title), '@contact' => $types['fields'][$fieldname]['widget']['label'], '@subject' => $edit['subject']));
