Description:
------------
levenshtein with 3 parameters does not work.
I have checked the soucecode, it treat the third parameter to be a callback function. While in the manual, it's supposed to be an integer.

Reproduce code:
---------------
levenshtein("abc", "abcd", 2);

Expected result:
----------------
2

Actual result:
--------------
Some warning message
