[Done v1.3.9e] Clearing quantity field on shopping cart should be the same as "0"

This is behavior that used to work in 1.3.8 and has been broken in 1.3.9. The fix is simple; in includes/classes/shopping_cart.php, above line 1535, add

if ($_POST['cart_quantity'][$i] == '') {
$_POST['cart_quantity'][$i] = 0;
}

If I enter 12 for a product and add to cart .. I see 12 ...

If I then, on the shopping_cart page, change the value to 0 it gets removed from the cart ...

Now if I change it to "nothing" as in blank, it goes back to 12 ...

Is this what you are meaning on this one?

Yes, exactly. I believe that clearing the field to nothing or blank should be the same as entering 0. This was the behavior in 1.3.8, and I believe it is the most intuitive response to this action. My small code fragment makes it work this way.
