0342b1f542 Sorting is now done using a sorting index rather than loading the entire 
result set into memory and doing a merge sort.  The old merge sort technique
was a carry-over from SQLite version 1.  The new method uses a bounded amount
of memory and scales to much larger result sets.  There are still errors:
some 39 regression tests fail. (CVS 2653)

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)
