This is basically a DFS to find leaf nodes. It will help omit duplicated parent ids early.
If merge-heavy history was abandoned, intermediate parent chains can have tons of duplicates, and the process explodes soon. Instead, we can skip any parent ids that have been remapped. We can no longer detect cycles reliably, but I think that's okay so long as the function terminates. Fixes martinvonz#4352
