Test strcspn() function : usage variations - with heredoc strings, varying mask & default start and len args

 * 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
