Since archiver.py was revamped in 95beb51158b58bcb9fdb1371af7699b72598ac34, import-mbox.py can no longer pass the ignore_body setting to archiver.py
This is because the top-level iBody variable in archiver.py no longer exists. I think the communication between import-mbox and archiver needs a rethink. AFAICT all the configuration settings are fixed for the life of the script, so it does not make much sense for them to be passed to Archiver class methods such as compute_updates. It seems to me that all the settings should all be passed across when creating the Archiver, and no args passed directly to class methods. Agreed?
