It turns out I was a little over-strict in my handling of EOF in
pscp.c when I did the big revamp in r9279: I assumed that in any SCP
connection we would be the first to send EOF, but in fact this isn't
true - doing downloads with old-SCP, EOF is initiated by the server,
so we were spuriously reporting an error for 'unexpected' EOF when
everything had gone fine. Thanks to Nathan Phelan for the report.
