I think Kamesh is saying that there are two routes we might takes with this
logging stuff:

   - add new items at the ends of their respective lines, as a sort of
     backwards-compat attempt

   - have revisions always be at the ends of lines, for more consistent
     parsing

and then he points out that the two routes are already in conflict because
in 1.5.0-dev we've added new fields that aren't revisions.
