>Description:
	If you push Control-D to ftp clients login-id query it
	probably follows NULL and sends garbage to the remote end
	with USER command.
>How-To-Repeat:
	911.pooh:~> ftp ftp.funet.fi
	Connected to nic.funet.fi.
	220-Hello UNKNOWN at pooh.tky.hut.fi,

	Name (ftp.funet.fi:tri):
    ***PRESS CONTROL-D HERE
	331 Password required for [GARBAGE HERE].
	Password: 
    ...
>Fix:
	Should be quite straitforward.  If login-name query returns NULL,
	then use default or abort if none available.  Or something.
