The last two ones seem to have gone.

I can't find my last week report in any category. What is the current status
of http://news.povray.org/uoj68uk5m391emvphovqfbg5vl0en7h2q6%404ax.com ?

That it will be added to the next posting of the list :-)

The category it will be in (officially confirmed / not confirmed) depends on
your ability to provide a shorter example.

  I think it was pretty unclear whether it is a bug or just a design
decision.
  If you can convince me that it's a bug, I can add it.

  Is only the problem described in them gone, or the actual bug they are
referenced in?
  If it's the former case, then those reports were not related to the bugs
in question and thus I should remove them from there.
