This doesn't work, and also seems unnecessarily complicated. (Why not just
use `--qf '%{sourcerpm}` as in my original question?)

But in any case, it doesn't solve my problem, as it just gives filenames,
and there's no way to know when a name ends and a version starts, as they
both use - as a separator.

rpm would be a tiny bit faster, if it could tell this. But it seems to not
have an easy way. And in fact if you use `dnf repoquery --installed`, it
is smart enough to just work from what's there locally. (You can use -C if
you want, but you don't have to.)
