With this change we'll not show an "Addresses" field for machines that we don't know any addresses for. This changes print_addresses() to never suffix its output with a newline, leaving that to the caller. That's a good idea since depending on who the caller is, different rules apply: if no addresses are found, then the list view still wants a newline, but the status view does not. This also changes the function to return the number of found addresses, which can be used to decide when to add a newline or not.
