I'm looking through this patch now.  It looks mostly good, but I am
wondering just exactly what is the rationale for adding comment
statements to the data structures, rather than ignoring them as before.
It seems like a complete waste of logic, memory space, and cycles;
moreover it renders the documentation's statement that comments
"are ignored" incorrect.  I did not find anything in the patch history
explaining the point of that change.
