Misguided PHPdoc comment in wp-load.php

[sambauers]

The follow paragraph in the PHPdoc comment in wp-load.php is incorrect:

 * Also made to work in the wp-admin/ folder, because it 
 * will look in the parent directory if the file is not 
 * found in the current directory.

That is not the purpose of the routine which searches for wp-config.php in the parent directory, It should be removed or rewritten something like:

 * Will also search for wp-config.php in WordPress'
 * parent directory to allow the WordPress directory
 * to remain untouched.
