f5905aa7be NULL values are distinct. A comparison involving a NULL is always false. 
Operations on a NULL value yield a NULL result.  This change makes SQLite
operate more like the SQL spec, but it may break existing applications that
assumed the old behavior.  All the old tests pass but we still need to add
new tests to better verify the new behavior.  Fix for ticket #44. (CVS 589)

ad3cab52fe Split the IdList structure into IdList and SrcList. SrcList is used to 
represent a FROM clause and IdList is used for everything else.  This change
allows SrcList to grow to support outer joins without burdening the other
uses of IdList. (CVS 584)
