I confirm that this bug does exist. It's especially annoying since we use here 
a lot of scripts which check for the return values of scp to indicate success 
or failure.

In fact it does the good thing on nonexistent files/dirs/etc, but fails in case 
of auth failure, name resolution failures and so on (the number after "rtfm" in 
the prompt reports the cmd exit status):
