Fixed bug: for RLogin and SSH, if an invalid (e.g. blank) passsword was
provided during the handshake, an "Invalid Logon" would be displayed followed
by a "Passowrord: " prompt, giving the user an opportunity to reenter the
correct password. Only problem: this only worked for sysop accounts. Normal
users would just be disconnected after they entere (any) password, correct
or not.

This bug is very old in the RLogin support and appears to have been copy/pasted
for the SSH Login bit too.
