As I mentioned in the previous message, my test shows that README is
correct in that via-branch values 1 and 2 refer to incoming via
headers. That is why there exists the extra value, which allows taking
via-branch value from "extra_id_pv" variable.

The question has been, what value could I assign to extra_id_pv to
uniquely identify the branch.  Since $T_branch_idx exists, perhaps a
good choice could be $sel(via[1].branch) + $T_branch_idx.
