This is somewhat a sad change, as the returned value is designed to
be useful if caller wants to continue appending to the list.
Now such a caller has to tangle the list (the variable it gave the
function as the fourth argument) itself to find its tail.
Does it really "confuse" readers enough that it hurts to have a
return value?
