Move limit from 200 bytes to 250 bytes - 5 left over just cause (+4 bytes for the $1 and $2). The other auto-summary still uses 200 as the limit (I suppose they don't want it too big or soemthing?).
if ( is_object( $rt ) && ( !is_object( $ot ) || !$rt->equals( $ot ) || $ot->getFragment() != $rt->getFragment() ) ) {

str_replace( "\n", ' ', $newtext ),
- max( 0, 200 - strlen( wfMsgForContent( 'autoredircomment' ) ) ) );
