addrevision: handle code path not producing delta We would like to be able to exit the delta generation block without a valid delta (for a more flexible control flow). So we make sure we do not expand the "delta" content unless we actually have a delta. We can do it one level lower because 'delta' is initialised at None anyway. Not adding a level to the assignment prevent a line length issue.
