Bug description:  increment operator works different than plus operator

Description:
------------
Applying the increment operator (++) on a variable (containing a number)
ending with a newline character doesn't change the variable.

However, applying += 1 to the same variable does result in the right
behaviour.

Reproduce code:
---------------
function showsucc($x)
{
  // using increment operator
  $tmp = $x; $tmp++;
  echo "successor of $x = ",$tmp,"\n";
  // using plus operator
  $tmp = $x; $tmp += 1;
  echo "result of $x + 1 = ",$tmp,"\n";
}

showsucc("123\n");
showsucc("123");


Expected result:
----------------
successor of 123
 = 124
result of 123
 + 1 = 124
successor of 123 = 124
result of 123 +1 = 124

Actual result:
--------------
successor of 123
 = 123 <---- difference is here

result of 123
 + 1 = 124
successor of 123 = 124
result of 123 + 1 = 124
