If the change of a PR has already been merged to the target branch elsewhere, the PR will not be auto-closed by GitHub - and will still show the same original diff. Still, the temporary merge commit is actually empty. This causes all kinds of strange CI behavior, from not showing rebuilds to not pinging maintainers. We check the merge commit during labeling anyway, to see whether a merge conflict is present. It's easy to just look a the number of affected files in this merge commit - and if there are none, we can just automatically close the PR as no longer relevant.
