It's very useful to annotate subtree commits (whether manually or via --annotate option) to differentiate them from super repository or another subtree commits.
But if I want to export a subtree as a standalone repository, or push those commits to that already existing repository, it would be nice to remove that annotation, since it makes no sense when it no longer belongs to a subtree, but to a single repository.
Is there any way to remove the annotation in those cases?
