Excellent, why didn't I see that? Now I wonder if there's a way to get du
to skip the intermediate totals so I can drop the "tail". And apparently
some files have the ever-cursed space in their names, so I haven't figured
out how to make the script deal with them.
(I don't want it human-readable since it's hard to sort, so I'll drop the
"h".)

Done that part:
dpkg-query -l '*' | grep ^ii | tr -s ' ' | cut -f 2 -d ' '
Anyone know a faster or cleaner way?

dpkg -L $PACKAGES | tr '\n' '\0' >> /tmp/files
du --files0-from /tmp/files
Or something like that.
