	% scp bela:/bsd nohow:/tmp

actually executes:

	% ssh bela 'scp /bsd nohow:/tmp'

so authentication from host 'bela' to 'nohow'
has to work without user interaction.
the localhost does not authenticate you to both
remote hosts (only to bela).

note that the name 'nohow' is interpreted on host 'bela'.
