* Revert "AUP3: Don't delete sample blocks prematurely" This reverts commit c1884349d595a2fb889c90f209ea4af3d1c70e1d. * "Don't delete sample blocks prematurely" fixed otherwise... ... and very simply. Problem was that, only for an interactive effect (like Bass and Treble), the save point was created, rolled back, created again, then committed. But (unlike with the non-savepoint commands, even if savepoint is outermost), rolling back a savepoint really just rewinds it without removing it -- therefore the second savepoint was inner, but the first (outer) was never committed, so some changes failed to persist. Solution: add a commit after rollback of savepoint to implement destructor of AutoCommitTransaction. The reversion of c188434 also leaves AutoCommitTransaction as a better RAII style operation. Rollback changes by default -- keep changes only if success is explicitly indicated. * Rename AutoCommitTransaction as TransactionScope... ... More appropriately, since it's now the rollback that is automatic but the commit that must be explicit
