[shrug...] I'd counsel leaving this as-is.  We've practically always
regretted it when we made the parser discard information about what
the user typed.  For instance, I was just reminded yesterday that we
really ought to distinguish SortClauses created due to user ORDER BY
clauses from those created because the parser silently added 'em.
