   2 -- Adds rev_text_id field to revision table.
   3 -- This is a key to text.old_id, so that revisions can be stored
   4 -- for non-save operations without duplicating text, and so that
   5 -- a back-end storage system can provide its own numbering system
   6 -- if necessary.
   7 --
   8 -- rev.rev_id and text.old_id are no longer assumed to be the same.
