Backward compatibility is maintained, i.e. you can restore ANY version backups without problems in 1.5. When "adding backup data to an existing course", no blocks are added. I 'm not sure what the correct behavior would be in this case. When restoring a backup from Moodle <= 1.2, the new course SHOULD be given default blocks when it is restored. I have not actually tested this, my tests were with version 1.3 and 1.4 backup format.
