Description:
------------
Hello, today I discovered bug (I think) which occurs in parsing shorthand ifs. It happens when we use shorthand if in shorthand if without braces.

Test script:
---------------
<?php

    echo (true ? "a" : (false) ? "b" : "c");

    //Output is: `b` instead of `a`.
    //Java and C# tells it's `a`
?>

Expected result:
----------------
to see letter `a`

Actual result:
--------------
b

It does provide valid output, when 2nd part of the statement is enclosed in brackets:

<?php
echo (true ? "a" : ((false) ? "b" : "c"));
//Output: a
?>
