Returns arguments from the current process starting
with argument number n, up to argument m. If there are less than n
arguments, or the arguments cannot be retrieved from the current
process, the empty string is returned. If m is smaller than n then
all arguments starting from argument n are returned. Argument zero
is traditionally the command itself.
