+** The list returned by 'overlays-at' is now in decreasing priority order.
+The documentation of this function always said the order should be
+that of decreasing priority, if the 2nd argument of the function is
+non-nil, but the code returned the list in the increasing order of
+priority instead.  Now the code does what the documentation says it
+should do.
