This is resolved; I was mis-reading the notation. I took it to mean that
the grammar must be LR(k) when all indentation constraints were erased.
That's not what it says at all. It's saying that productions are taken from
δ rather than δ'. But δ is the production relation for an IS-CFG, defined
in section 4. Productions are drawn from N X ((N ∪ Σ) X I)*. Which is to
say: they are annotated with indentation relations.
