Package: ssh
Version: 1:4.7p1-5
Followup-For: Bug #254909

If you pass -f to ssh without supplying a command to be executed on the
remote system, you are told:

    Cannot fork into background without a command to execute.

As an alternative to supplying a command, you can in fact pass -N, which
is documented in ssh(1) thusly:

    Do not execute a remote command.  This is useful for just forwarding
    ports (protocol version 2 only).

Perhaps the error from a commandless -f should end with "(try -N)"?
