 * Means a minimum of 2x as much time spent resolving dependencies,
   at least in my simple implementation, which re-runs the dependency
   resolution loop until no new pages are rebuilt.
+  (I added an optimisation that gets it down to 1.5X as much work on
+  average, still 2x as much worst case. I suppose building a directed
+  graph and traversing it would be theoretically more efficient.)
 * Causes extra work for some transitive dependencies that we don't
   actually care about. For example, changing index causes
   plugins/brokenlinks to update in the first pass; if there's a second
   pass, plugins/map is then updated, because it depends on plugins/brokenlinks.
   (Of course, this is just a special case of the issue that a real
   modification to plugins/brokenlinks causes an unnecessary update of plugins/map,
-  because we have only one kind of dependency.)

+  (Fixed now for cases like this one where contenless dependencies avoid
+  the unnecessary work.)
