Unfortunately they are all related.  "localhost" as a single label
gets the search list applied, then is tried as is.  "_foo._tcp.localhost"
as a multi-label string gets tried as is then the search list is
applied.  localhost is the one pre-hierachical hostname that we still
use.  Other single label hostnames are intended to be short cuts to
a heirachical hostnames.
