-- Convert watchlists to new new format ;)
-- Ids just aren't convenient when what we want is to
-- treat article and talk pages as equivalent.
-- Better to use namespace (drop the 1 bit!) and title

-- Check that the new one is correct, then:

-- Also should probably drop the ancient and now unused:
