As it looks like we won't reach any simple conclusion soon, I have moved
the target for this bug tracker resolution to 0.70.0. It appears there
is no way to fix \predisplaydirection quickly and to everybody's liking
without ending up in a tricky backward compatibility problem and that,
I don't want to do in the stable release branch, sorry.
We will sort out all this direction stuff in version 0.70.0.
