Implicit Transactions

[gramian]

This is a three part question concerning implicit transactions:

1. Is an IMPORT DATABASE command automatically a transaction? If so I will put it into the docs.
2. Is the IMPORT DATABASE command closing all open transactions? I am asking because BEGIN; IMPORT DATABASE ...; COMMIT; errors at the COMMIT with "No open Transaction".
3. Should a LOAD command in the console be an (implicit) transaction? The reasoning behind this is that if something is worth putting into a script file then it is significant enough to ensure it is finished.
