Description:
------------
Using Short Conditionals with more lines is causing wrong results:

Reproduce code:
---------------
   $x = 7;

   echo 
      $x == 5 ? 'five' : 
      $x == 6 ? 'six' : 
      $x == 7 ? 'seven' : 
      $x == 8 ? 'eight' : 
      $x == 9 ? 'nine' : 
      null;  

Actual result:
--------------
Returns 'nine'. Multiline Short Conditionals fail.

It's the operator presedence. For more info:

Does it make sense to use such confusing left-to-right presence, while other program languages like Java and C operate from right-to-left?
