+PH/04. Change 4.11/85 fixed an obscure bug concerned with addresses that are
+       redirected to themselves ("homonym" addresses). Read the long ChangeLog
+       entry if you want to know the details. The fix, however, neglected to
+       consider the case when local delivery batching is involved. The test for
+       "previously delivered" was not happening when checking to see if an
+       address could be batched with a previous (undelivered) one; under
+       certain circumstances this could lead to multiple deliveries to the same
+       address. A one-line patch to add the appropriate test fixes the bug.
