Test strcspn() function : usage variations - different strings with default start and len args

/* Prototype : proto int strcspn(string str, string mask [, int start [, int len]])

* Description: Finds length of initial segment consisting entirely of characters not found in mask.
|

If start or/and length is provided works like strcspn(substr($s,$start,$len),$bad_chars)

* Source code: ext/standard/string.c

* Alias to functions: none
