Does this imply that if you've moved results from 'platform/mac' to
'platform/mac-leopard' when you switched from 10.5 to 10.6? (Since,
presumable, some results that were in platform/mac were actually
specific to 10.5?)

I would've expected a different model, where if the output differed by
version, then you had results in 'mac-leopard' and 'mac-snowleopard',
and the presence in 'mac' meant it should be the same across both
(this was the approach I was planning to use for Chromium, which is
just starting to run into this problem with XP/Vista/Win 7). I can see
some advantages to your approach, but it seems more confusing in the
long run.
