Well, just "$@" doesn't fully help. It quotes the stuff just for the
echo(1) call itself, but after echo(1) outputs the stuff to stdout
the quotes will be gone anyway. There is only one possibility in
Bourne-Shell: to use a "for" loop to iterate over the arguments and then
re-construct the stuff in a quoted way.
