Just noticed my name in this thread! :)
In the past we took the view that we must be able to produce old checklists verbatim and so tweaking the names and checklist entries to correct obvious errors was frowned upon. But I am trying to be far more pragmatic with this - especially with lists that I would term "unpublished lists" where they have been used in Recorder but never actually appeared in print. The obvious example is the Recorder 3.3 list which has contained numerous ill-formed names and typos and I correct these on a case-by-case basis :)
