Having said all that, I suspect that this problem is not new and certainly not caused by this topic. We should have unconditionally died when GIT_ATTR_SOURCE gave a blob object name, but pretended as if an empty tree was given. There may even be existing users who now assume that is working as intended and depend on this bug. So, let's leave it as a "possible bug" that we might want to fix in the future, outside the scope of this series.
