Description:
------------
Alternative syntax for if has a bug when you do not use brackets


Reproduce code:
---------------
<?
function test($a){
  return $a==1?'one':$a==2?'two':$a==3?'three':'more';
}

print(test(1).'<br/>');
print(test(2).'<br/>');
print(test(3).'<br/>');
print(test(4).'<br/>');
?>

Expected result:
----------------
one<br/>two<br/>three<br/>more<br/>

Actual result:
--------------
three<br/>three<br/>three<br/>more<br/>
