Hello,
while trying to upgrade from 1.5 to 3.1 i noticed that between t_relay() and branch_route, $du gets automatically set to $ru if it has not been set before.
This is a change from 1.5 i could not find documentation for, so it might have been unintened.
Can someone enlighten me on the purpose of this change and if there is a way to determine if $du is (was) unset other than comparing $ru to $du, wich seems a bit inefficient?
Is it even guaranteed that $du gets set to $ru in every possible scenario?
