+The --all flag should fix anything that wouldn't cause a problem if you fixed
+it, including the working copy. Obsolete revisions are not fixed because that
+could cause divergence. Public revisions would cause an abort because they are
+immutable. We can fix orphans because their successors are still just orphans
+of the original obsolete parent. When obsolesence is off, we're just fixing and
+replacing anything that isn't public.
