CI hates juju, maybe the feelings are mutual

[John Meinel]

Actually, I was trying to fix it, and it is more broken than we realized.
We no longer support multiple extra arguments to SCP. It always complains
if there is one that isn't exactly the last one. (-o "foo" says it isn't
accepted, -o"foo" is allowed, but you can't supply 2 of them, etc).
It just needs to be fixed.
I think a better way is to allow "--", but just interpret each argument as
potentially a target, and expand it if it has a clear MACHINE_OR_UNIT: at
the beginning.
