ABSPATH definition - incorrect on chrooted vhost

[dacartpl]

ABSPATH defined in wp-load.php (and in other files) returns incorrect string on chrooted vhosts (double slash '/' instead of a single):

<?php
if ( ! defined( 'ABSPATH' ) ) {
        define( 'ABSPATH', dirname( __FILE__ ) . '/' );
}

On chrooted vhost - output of dirname( FILE ) is '/' and no need to add additional '/' at the end of string.

It would be nice if the ABSPATH definition looked like the following:

<?php

if ( ! defined( 'ABSPATH' ) ) {
        define( 'ABSPATH', ('/' === dirname( __FILE__ )) ? dirname( __FILE__ ) : dirname( __FILE__ ) . '/' );
}
