Changes between Initial Version and Version 1 of Ticket #19263, comment 4

-              initial
+              v1
 This query failed:
+{{{#!python
 Book.objects.filter(author__in=Author.objects.empty()[0:0])
+}}}
 while this succeded:
+{{{#!python
 Book.objects.filter(author__in=Author.objects.empty())
+}}}
 Instead of later returning empty sql string, a QuerySet with equal indices is now immediately converted to QuerySet.none().
