OTOH if I'm already reading a package's changelog file, I have probably
exhausted most other documentation, including README.Debian and
NEWS.Debian if present. Unless I'm reading it during upgrade of course.

If you agree with that, then implementing that with a merged changelog
would require some considerable munging/grepping of the changelog, would
it not?

OTOH, I really like 2a, as I don't always make it to the end of
apt-listchanges output during a large upgrade.

Ok, well I don't know how to tell if you are in the minority. In the old
thread I think you were mostly alone in wanting a separate file.

Yes a temp directory is probably a good idea.
