The following code should work in both PHP 5.5 and earlier, and in both PmWiki  
2.2.58 and earlier (last line only):

  return preg_replace_callback('/<(\\w+\\s)(.*)$/s',
     create_function('$m', "return '<'.\$m[1].Keep(\$m[2]);"),

See the pages http://php.net/preg_replace_callback and  
http://php.net/create_function for more information.
