Whilst it is functionally compatable with a real /bin/test most of the
time, it does fall down when quoted strings containing white space are passed 
as arguments.

eg:
	newtest "hello there" = "hello there"

But this is really a problem with $* breaking the arguments up.

>From sh(1) man page, under the section on Quoting,

	"$*" is equivalent to "$1 $2 ..."
and     "$@" is equivalent to "$1" "$2" ...

So the script should really be:

	:
 	# /bin/test
 	if [ "$@" ]
 	then
 	  exit 0
 	else
 	  exit 1
 	fi

This version works much better.
