 OPTIONS
 -------
 
+--stale-fix::
+       This revamps the logic -- the definition of "broken commit"
+       becomes: a commit that is not reachable from any of the refs and
+       there is a missing object among the commit, tree, or blob
+       objects reachable from it that is not reachable from any of the
+       refs.
++
+This computation involves traversing all the reachable objects, i.e. it
+has the same cost as 'git prune'.  Fortunately, once this is run, we
+should not have to ever worry about missing objects, because the current
+prune and pack-objects know about reflogs and protect objects referred by
+them.
