Chain of Consequences
Sometimes one small missing thing starts a whole chain of consequences: no nail, then no shoe, then no horse, and so on. The function proverb receives a list of words items and builds proverb lines for each adjacent pair. Add the final line about the first item in the list, and return an empty list if items is empty.
