This may need to be fixed on osm2pgsql to handle this situation and
add either tunnel or covered tags to the way so they render properly
without adding redundent information.

My take on the covered tag was for ways that are covered by a roof,
but not a building, so tagging a way under a building shouldn't be
needed as you said.
