030530de9b Make sure USING and NATURAL work on joins even if the columns are renamed 
using an AS phrase.  Ticket #523. (CVS 2233)

47a6db2bfd Column names coming back from a SELECT are now just the name of the 
source column without the "table." prefix. In other words,
"PRAGMA short_column_names=ON" is now the default.
This makes the names of columns behave more like other SQL engines.
The old behavior can be restored by setting "PRAGMA short_column_names=OFF". (CVS 2231)

also make the implementation of correlated subqueries easier. (CVS 2228)
