what would you call a git commit that can no longer be reached from any branch or reference (for example because you ran `git commit --amend` or `git rebase`), but that you can still get to from `git reflog`?
I've considered "orphan", "dangling", and "unreachable" but none of these seem right:
- orphan has another meaning in git
- dangling only refers to the "tip" commits
- "unreachable" means that you can't reach it at all
