Code review comment for lp:~waigani/juju-core/cmd_help_aliases_1299120

This breaks compatibility in some places, and we can't do that. The
changes in cmd/juju are fine, but anything that changes what we send
over the wire for the API is not.

cmd/juju/removemachine.go:77: return

Replace?

state/api/client.go:378: // ServiceDestroy destroys a given service.
What about service? Did we keep "destroy" for service but "remove"
everything else? that seems somewhat incoherent to me.

This Replace is surprising to me. Just a typo, or something deeper I
haven't figured out?

We definitely can't change the stuff we call() -- we need to keep
working with old servers.

Yeah, please just don't touch the API at all. We can use the better
names with new api versions -- when we get versioning -- but for now
this is just a break.

(ok, *this* is not -- the names of the types aren't reflected in what we
sent over the wire)
