Comment 2 for bug 514864

For Canonical Partners, we should use "Canonical Partners", and for purchases we should use something like "Purchased software". I don't know what we could do for other sources, though. And in a future version I expect we'll be able to add arbitrary sources directly from USC rather than going into Software Sources, so this bug will become steadily more important. Ideally we'd use the Label of the archive, but I guess there's a catch-22 there in that we don't know the Label until after the repository data has loaded, which is after we've already added the line to sources.list.
