// macro	str_cpy_rep
//
// purpose	Copy to the target string the contents of the source string,
//		with all occurrences of the pattern string replaced by the
//		replacement string.
//
//		If entire resultant string will not fit the available space,
//		then rollback everything leaving the original target empty.
//
// arguments	1 (char *) pointer to beginning of target string
//		2 (size_t) total maximum length of target string
//		3 (const char *) pattern string to be matched in source
//		4 (const char *) replacement string to replace each pattern
//		5 (const char *) source string to be appended to target
//
// returns	(size_t) final length of target string
//		(size_t) ~0 : error
//
// note		Contents of target string space will be overwritten if there
//		is insufficient space to complete the copy.  Nothing should
//		be stored there, anyway.
