order of firstname and lastname in filling forms

Whatever the value of fullnamedisplay is, input areas of user's firstname and lastname are ordered as this order. Japanese users (maybe also other Asian users) often make mistakes in inputting their names. I proposed it should be changable according to fullnamedisplay like this:

<?php

$nameordercheck->firstname = a;

$nameordercheck->lastname = b;

if ( fullname($nameordercheck) == b a )

else

?>

This modification should be added to login/signup_form.html and user/edit.html.

A complete patch for this is :
