Just to clarify - you've queued this series that I posted, not the above 'UNTESTED' branch where I tried (unsuccessfully) to bring in the prerequisites. (The position of your comment made me jump!) The background is Greg commented on the BHB list that he thought it would be better to bring in the prerequisites, I said I'd have a go. As described here, I think it just creates new problems.
