The former copies file 'c' from user 'a' at host 'b' to the current
user at host 'd'.

The latter does the same, but via a file c in the current directory
on the current host.

What I am asking is why the former can succeed but the latter fail if
the local machine can log into both hosts. IE authenticating to
each of them individually works, but not when they are both on the
same scp command line.
