Nobody answered (or maybe cared? :-) )

I propose to document the slightly odd behaviour with this wording:
The literal value <literal>localhost</literal> in the hostname field 
matchesan empty hostname connection parameter as well as matching its literal 
value.This can be useful for specifying Unix-domain socket connections.
