Currently ssh_authorized_key has some logic about $user being false or
'', but it sets its value to default to 'root'.
So, in order to use the name as the user's name, one has to clear the
user parameter, which is totally redundant.
Since it is sometimes useful to publish multiple keys for a user, the
$user parameter is useful.
To make using ssh_authorized_key for one-key normal users simpler, make
$user default to being empty (which will use $name as the user name).
'root' can always be specified either via the name or by the $user
paramter.

When one uses the $name to define the user that should receive an SSH
key, setting $user to a negative value, ssh_authorized_key currently
creates the authorized_keys file under /home/.ssh/authorized_keys
Fix this by changing ${user} to ${real_user} in the key's path.
