Doesn't notice if a file is deleted outright

[ferdnyc]

If I have a package example-tool installed that owns a file /etc/example.conf, then any edits I make to /etc/example.conf will be shown when running sudo dnf diff example-tool. (Or the more specific sudo dnf diff example-tool /etc/example.conf.)

But not so, if the file is deleted outright:

$ sudo sh -c "echo '\n# Additional config\n' >> /etc/example.conf"
$ sudo dnf diff example-tool

Seems like it should emulate git in that scenario, and show the entire file's contents as deleted:

$ mkdir -p /tmp/deletion-test
$ cd /tmp/deletion-test
$ git init
$ cp /etc/os-release .
$ git add os-release
$ git commit -m "import"
$ rm os-release
$ git diff
