Ok, that's what we'll do.  Of course we'll still list the \fooUp
commands in the @predefined sections, but we won't give any other
explanation about them.

Nope; re-creating the IR.  For directions, which can be controlled
with ^ and _, it makes sense.  For the other things, the effort
would be better spent improving the IR directly.

Side note Mats: ^_ were introduced for ties about six months ago,
