Multiplying NULL by zero gives NULL, not zero. I misread the test data and coded it wrong. This check-in fixes the problem. (CVS 601) (check-in: df9cc852 user: drh tags: trunk)

Refinements to NULL processing: NULLs are indistinct for DISTINCT and UNION. Multiplying a NULL by zero yields zero. In a CASE expression, a NULL comparison is considered false, not NULL. With these changes, NULLs in SQLite now work the same as in PostgreSQL and in Oracle. (CVS 600) (check-in: da61aa1d user: drh tags: trunk)
