/usr/bin/test message forgets newline

[jidanni]

/usr/bin/test neglects adding the trailing newline for this message at
least:

# /usr/bin/test -d 1 2 3 2>&1|od -c
0000000   /   u   s   r   /   b   i   n   /   t   e   s   t   :       e
0000020   x   t   r   a       a   r   g   u   m   e   n   t       `   2
0000040   '
0000041

P.S.,
$ /usr/bin/test --help
$ /usr/bin/test --version
do nothing, in contrast to the man page. (But not the Info page.)
