It's typically when you define a function from within a macro so you may
have something like
`(...
(cl-defun ,foo (,@args &aux ,@auxargs)
,@body)
...)
where `auxargs` can have any length including 0. It's not
terribly hard to strip the &aux when `auxargs` is empty, but it's
convenient to be able to use the above form without having to worry
about a possibly empty `auxargs`.
