bug#14401: su - nobody -c emacs gives "Could not open file: /dev/tty"

[jidanni]

Odd,

# (unset DISPLAY; su - nobody -c emacs)
No directory, logging in with HOME=/
emacs: Could not open file: /dev/tty

doesn't work anymore. One needs two steps,

# (unset DISPLAY; su - nobody)
No directory, logging in with HOME=/
nobody@jidanni2:/$ emacs

Also one can test with su nobody with no -.
