Description:
------------
stream_wrapper_register( 'var', 'VariableStream' );

__autoload get 'variablestream' as parameter [ in lower case ]

but in other situation:
new VariableStream();

__autoload get 'VariableStream' as parameter.

this is inconsistent. 

I prefer the case sensitive way. :)


Reproduce code:
---------------
VariableStream.class.php:
<?php 
class VariableStream {
    function __call() {}
}
?>

VariableStream2.class.php:
<?php 
class VariableStream2 {
    function __call() {}
}
?>

index.php:
<?php
function __autoload( $class ) {
    echo $class, "\n";
    include_once( $class . '.class.php' );
}

stream_wrapper_register( 'var', 'VariableStream' );
new VariableStream2();

?>

Expected result:
----------------
VariableStream
VariableStream2

Actual result:
--------------
variablestream
VariableStream2
