Changes to code to allow multiple password change

I recently discovered that this plugin does not allow a user to change the multiple passwords if the option to prevent password duplication is activated. I have this option activated as I need different passwords for different pages in a given hierarchy.

I have changed the following code:

if( $bawmpp_options['clone_pass']!='on' ){
	$ids = implode( ',', $a_ids );
	$wpdb->query( $wpdb->prepare( 'UPDATE ' . $wpdb->posts . ' SET post_password = %s WHERE ID in ( ' . $ids . ' )', $_POST['post_password'] ) );
	$multiple_passwords = array_filter( array_map( 'trim', explode( "\n", $_POST['multiple_passwords'] ) ) );
	foreach( $a_ids as $post_id )
		update_post_meta( $post_id, '_morepasswords', $multiple_passwords );
}

to the following, which allow the modification of passwords regardless of the password duplication option:

if( $bawmpp_options['clone_pass']!='on' ){
	$ids = implode( ',', $a_ids );
	$wpdb->query( $wpdb->prepare( 'UPDATE ' . $wpdb->posts . ' SET post_password = %s WHERE ID in ( ' . $ids . ' )', $_POST['post_password'] ) );
	$multiple_passwords = array_filter( array_map( 'trim', explode( "\n", $_POST['multiple_passwords'] ) ) );
	foreach( $a_ids as $post_id )
		update_post_meta( $post_id, '_morepasswords', $multiple_passwords );
} else {
	$wpdb->query( $wpdb->prepare( 'UPDATE ' . $wpdb->posts . ' SET post_password = %s WHERE ID = ' . (int) $_POST['post_ID'], $_POST['post_password'] ) );
	$multiple_passwords = array_filter( array_map( 'trim', explode( "\n", $_POST['multiple_passwords'] ) ) );
	update_post_meta( (int) $_POST['post_ID'], '_morepasswords', $multiple_passwords );
}

The modifications were made in the file backend-noajax.inc.php, inside the inc directory, starting at line 153 (inside the bawmpp_update_password function).

This solved my problem entirely but I think the changes (or some similar update to the code) should be put in the trunk and a new version published so that people with the password duplication prevention option activated can change their passwords.
