Bug description:Metaphone returns fewer phonemes than defined

Description:
------------
Under certain conditions, the metaphone function returns fewer phonemes
than the $phonemes parameter specifies.  This is an edge-case occurrence
when dealing with an X near the end of the specified phoneme count.

For the test script, the following phoneme transformations take place:
A -> A
X -> KS
C -> K

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

var_dump('axccc', 2);  // Should produce AKS
var_dump('axccc', 3);  // Should produce AKSK as "X->KS" is one phoneme
var_dump('axccc', 0);  // Should produce AKSKKK

?>

Expected result:
----------------
string(3) "AKS"
string(4) "AKSK"
string(6) "AKSKKK"

Actual result:
--------------
string(3) "AKS"
string(3) "AKS"
string(6) "AKSKKK"
