So can I assume you're confirming that if I do this the format code
will handle the four cases I included in my testcase?  If so, great.

Regarding levels of indirection, I am aware of the "pointer_count"
field, if that's what you mean.

What I can't figure out is how to obtain a "TREE_TYPE" from the result
of calling maybe_get_identifier ("tree_node") that is suitable for
stuffing into the format data table.  I'm sure it's just a couple of
lines of tree twiddling, but I can't figure out the appropriate magic

Can you shed some light on that?
