debian-changelog-mode doesn't seem to work for me

[Bob Hilliard <hilliard@debian.org>]

     Some time in the past year, debian-changelog-mode has stopped
working for me.  I have dpkg-dev-el v. 1.10-1 installed, and `mode:
debian-changelog' at the bottom of the affected changelog files.  I
use emacs19, v.19.34-26.5.

     I can't find any documentation in the dpkg-dev-el package.
