This is interesting. I like it!

And it defeats the purpose. We want to delete the existing
entries, not add different ones.

Okay. It's sometimes hard to the sense or tone in email. I just
want to be able to do it without patching Emacs itself (so we can
use it right away).

We already use a similar scheme in /etc/emacs/site-start.d/50dpkg-dev.el
to load debian-changelog-mode on changelog.Debian.gz files. But we
don't want to load debian-changelog-mode on an upstream
/usr/share/doc/changelog.gz file, only on Debian native ones. We can't
use the name to tell them apart.

Done with add-hook instead of setq, this is an interesting answer.

Thanks all! I have two good candidates to try out. I'm sure we'll soon
be able to remove all traces of the local variable block from changelogs
without losing any benefit.
