That someone was me. I have been doing a lot of tidy-up work on  
boundaries across England, removing duplicate ways and parallel ways,  
adding coastal sections of boundary and have probably taken a few  
features backwards in the process for which I appologise.

One problem with OSM at present is that without citations for the  
information in Ways one doesn't know what the basis of a feature is  
and whether one has better information about it or not. Possibly their  
should be a section on the Bristol wiki page citing these sources or a  
'source:boundary' tag in the relationship although one might need  
multiple sources for a boundary.
