+       Fix bug #21192.  Thanks to John Darrington for review.
+
+       * casereader.c (casereader_read): Decrement case_cnt before
+       calling the casereader's "read" member function, so that we
+       interact properly with lazy_casereader.
+
+       * datasheet.c: Add regression test for above bug fix.
+       (clone_datasheet): New function.
+       (lazy_callback): New function.
+       (check_datasheet_casereader): New function.
+       (check_datasheet): Check datasheet contents are reported correctly
+       through an ordinary casereader and a lazy casereader.
+       (clone_model): Use clone_datasheet.
