I think it's a little awkward this way; maybe it would be better as a
separate table column.  Or maybe it was better the way it was; I'm not
sure.  Or maybe we could have a separate table that just gives the
equivalences between stats table-column pairs and functions.  Of those
ideas, I think I like "separate table in the same column" the best.

Also, I wonder if we should promote section Other Statistics
Functions to 27.2.3.
