1)      This probably uses a loop (in strncpy)

2)      I don't know exactly what the standard C library does, but many
	string copy routines (in micro-code or higher level) check
	for overlapping strings and would process your request in reverse
	to avoid just the recursion you want.  (For instance, you may
	have a string in there to which you want to prepend a character.)
