Dave, Glad you are happy.
The truth is that you gained space via the backup/restore process. The data formats of 1.3.1 and 1.4 are the same. leveldb only removes dead / old key/values during its background compaction. It could be days, even weeks in some cases, between when you write fresh key/values and when their old version are discarded. Your restore process only put the fresh keys back into the database. The old versions were never part of the backup.
