Oh right. Copy/paste fail.

It does, doesn't it? I really would have loved to start resetting right
away, but if the list were not sorted and traversed at the same time as
the tree-ish, the performance would just be suboptimal.
I think that is an important point and I adjusted the commit message
accordingly.

True. I adjust the flags accordingly now.
