I wasn't talking about tagging, however there is 2 issues here,
tagging and how to get osm2pgsql to cope with this situation.
I wasn't suggesting we're tagging for mapnik/osm2pgsql just how mapnik
deals with it at present, which is part of the current problem on how
to get mapnik to render highway shields on a per country or per state
basis.

There is a lot of borders out there, and not just country borders,
state and other administrative borders too so unless something changes
like ref=* it shouldn't be broken up just because it crosses a border
that's for rendering software to cope with.

It's not about "feeling better" it's about presenting data
consistently for all software, then how each piece of software copes
is up to the author.
