Add original hostname to output of "ssh -G"

Hey!

In some occasions, it is interesting to be able to extract the host
provided as an argument. In my case, this is useful when wrapping the
SSH command to update the window title with the hostname or add
additional arguments depending on the target host. This can currently
be done with `ssh -G` but the returned hostname is the `Hostname`
option which may not match the hostname provided on the command-line.
In my case, it is often an IP address which is not helpful to display
as a window title.

Would it be possible to add the original hostname to the output of `ssh
-G`? Attached a tiny patch for this purpose.
