38640e15af All the code is now in place for SQLite to distinguish between NUMERIC and 
TEXT datatypes.  Still need to turn on the new code and test it. (CVS 659)

f570f011eb 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)
