Bug#459806: check arguments

[jidanni@jidanni.org]

Package: openssh-server
Severity: wishlist

One would think that a program so highly related to security would
check its arguments better before proceeding to stage II or whatever.

$ /usr/sbin/sshd --help
Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_dsa_key

Anything not understood should trigger a usage message.

Ah, it does check a little:
$ /usr/sbin/sshd -
Extra argument -.

But I note there is no correct documented way of getting a usage
message! One must trigger an error.

$ /usr/sbin/sshd -h
sshd: option requires an argument -- h
