setting DNS= (or DNS="") explicitely should not fallback, I agree with
that. There are people who want no DNS whatsoever and that should be
configurable.

But if extract_first_word() returned a non-empty string and
manager_add_dns_server_by_string fails (for all iterations of the loop),
it should definitely kick some fallback in -- the user obviously wanted
*something*, it just doesn't work.

Not sure where the configuration snippet with comma comes from but yes
ultimately it's "just" a configuration error.
Nevertheless, a config that somehow worked until a recent update through
fallback, I don't think we want more unhappy users :)
