Description:
------------
In the documentation
(http://www.php.net/manual/en/language.operators.increment.php),
"Example #1 Arithmetic Operations on Character Variables" shows how
strings can be incremented.
You would expect this to work the opposite way, too -- however, it
doesn't.
See the modified code from Example #1 attached.


Test script:
---------------
$i = 'W';
for ($n=0; $n<6; $n++) {
    echo --$i . "\n";
}


Expected result:
----------------
V
U
T
S
R
Q


Actual result:
--------------
W
W
W
W
W
W
