With the two helpers being very sketchy at this stage, it is very
hard to judge if they make sense.  At the conceptual level, I can
see that set-formatting-state is to allow an atom to affect the
state before the value of the atom is emitted into the buffer.
I cannot tell what perform-state-formatting is meant to do from
these call sites.
