- n->address is set to the e->address of the edge left of n to n.
- We are currently examining the edge e right of n from n:
-
- - If e->reverse->address != n->address, then e->to is probably
- not reachable for the nodes left of n. We do as if the indirectdata
- flag is set on edge e.
- - If edge e provides for better reachability of e->to, update
- e->to and (re)add it to the todo_tree to (re)examine the reachability
- of nodes behind it.
