non-informative error message

[Serafeim Zanikolas]

Hello,

The openssh client terminates with the following error message when unable to 
resolve a username: "You don't exist, go away!"

Leaving aside style and tone, the message is not informative. Please consider 
changing it to something more appropriate and helpful, such as "Unable to 
resolve username".

(The message appears in the files ssh-keygen.c and ssh.c, as of version 
openssh-4.2p1)

Thanks,
Serafeim
