-** Calculate min_str and max_str that ranges a LIKE string.
-** Arguments:
-** ptr		Pointer to LIKE string.
-** ptr_length	Length of LIKE string.
-** escape	Escape character in LIKE.  (Normally '\').
-**		All escape characters should be removed from min_str and max_str
-** res_length	Length of min_str and max_str.
-** min_str	Smallest case sensitive string that ranges LIKE.
-**		Should be space padded to res_length.
-** max_str	Largest case sensitive string that ranges LIKE.
-**		Normally padded with the biggest character sort value.
-**
-** The function should return 0 if ok and 1 if the LIKE string can't be
-** optimized !
