It's on the right track, but you still need to differentiate between the
cases where IFS is unset (in which case the positional parameters need to
be separated into individual words, and those individual words need to be
split on $' \t\n') and where IFS is null (in which case split_on_spaces is
used as an internal flag to satisfy the Posix requirement that $* expand
into separate words no matter what IFS is set to).
