    // When the same change has already been merged to the target branch, a PR will still be

    // open and display the same changes - but will not actually have any effect. This causes

    // strange CI behavior, because the diff of the merge-commit is empty, no rebuilds will

    // be detected, no maintainers pinged.

    // We can just check the temporary merge commit, and if it's empty the PR can safely be

    // closed - there are no further changes.

    // We only do this for PRs, which are non-empty to start with. This avoids closing PRs

    // which have been created with an empty commit for notification purposes, for example

    // the yearly election notification for voters.
