This script will not work correctly with arguments that are empty or
contain special characters.  (For example:

	if /bin/test "$foo" = ""; then exit; fi

would not work because the $* would expand to only "$foo =").  Use of
"$@" instead of $* fixes this, and here's another way of implementing
the /bin/test script:

	[ "$@" ]

Yes, that's right, just that one line will do it.
