Bug description:multiple $_POST array values not being assigned correctly

Description:
------------
The value of a $_POST array item is not being assigned properly

Test script:
---------------
<form method="post">

<input type="submit" name="step4[edit][change]" value="Submit and
continue">

<input type="submit" name="step4[edit]" value="Continue without changes">

</form>



<?

//After form submission

var_dump($_POST['step4']['edit']['change']);

?>

Expected result:
----------------
//When "Continue without changes" is pressed, expected value:

NULL

Actual result:
--------------
//When "Continue without changes" is pressed...



//Actual value:

string(1) "C"



//The "C" is taken from the first character of the value of
$_POST['step4']

['edit']



//A var_dump of $_POST['step4']['edit'] returns the value as expected as
does a 

var_dump of $_POST['step4']['edit']['change'] when that is actually
pressed.
