10.7.2 String predicates

Function: string-null? s
[SRFI-13] Returns #t if s is an empty string, "".

Function: string-every char/char-set/pred s &optional start end
[SRFI-13] Sees if every character in s satisfies char/char-set/pred. If so, string-every returns the value that is returned at the last application of char/char-set/pred. If any of the application returns #f, string-every returns #f immediately.

Function: string-any char/char-set/pred s &optional start end
[SRFI-13] Sees if any character in s satisfies char/char-set/pred. If so, string-any returns the value that is returned by the application. If no character satisfies char/char-set/pred, #f is returned.
