Eric's point was (I think) not about multiple entries for the same variable, but about multiple entries for different services, like
http.receivepack = 1 http.uploadpack = 0
The order of assignments to svn->enabled change, but it doesn't matter because svc is just a local variable pointing to the right element of rpc_service[i]. So in both cases, you'll assign
rpc_service[<index of service>].enabled = <last occurence of variable http.<service> >
even though the order of assignments will change.
Eric, am I interpreting right?
