very simple tcpd replacement

[Marcus Brinkmann <Marcus.Brinkmann@ruhr-uni-bochum.de>]

Hello,

I plan to provide this simple tcpd dummy in inetutils. Please let me know if
this can be improved, or if you think this won't work.

#!/bin/sh
# /usr/sbin/tcpd --- a dummy until we get the real one.

exec ${1+"$@"}

Thanks,
Marcus
