gdown/gup: add next/previous alias
Up and down refer to the customary order in log output rather than
concepts; as such, it may be confusing to the user. I for one found
them suprising -- they just didn't fit with my mental model.
Previous and next, however, imply a clear parent/child relationship.
We attroduce the new name as aliases for now.
