replacement of regular file with symlink not detected

[Habbie]

I have two packages:

$ for f in */pdns-backend-sqlite3_* ; do echo == $f ; dpkg-deb -c $f | grep /schema.sqlite3.sql ; done
== pdns-4.4.0.16.relauth44x.gc8b6f52df-debian-buster/pdns-backend-sqlite3_4.4.0+relauth44x.16.gc8b6f52df-1pdns.buster_amd64.deb
-rw-r--r-- root/root      3043 2021-01-12 16:29 ./usr/share/doc/pdns-backend-sqlite3/schema.sqlite3.sql
== pdns-4.4.0.21.debianupdate44.g1613283c0-debian-buster/pdns-backend-sqlite3_4.4.0+debianupdate44.21.g1613283c0-1pdns.buster_amd64.deb
-rw-r--r-- root/root      3043 2021-01-29 08:34 ./usr/share/pdns-backend-sqlite3/schema/schema.sqlite3.sql
lrwxrwxrwx root/root         0 2021-01-29 08:34 ./usr/share/doc/pdns-backend-sqlite3/schema.sqlite3.sql -> ../../pdns-backend-sqlite3/schema/schema.sqlite3.sql

The file was moved, and its old location was symlinked to the new one. However, pkgdiff reports the new location as 'added' and the old location as 'unchanged' - presumably because the content is still the same. I'd rather have seen some note that there was in fact a change, so I would know to have a look.

(By the way, thank you for pkgdiff, it's such an awesome tool!)
