Don't repeat how to upvote/downvote every line

Make the output more compact by telling the user what the
upvote/downvote commands once at the stop of the output
rather than for every entry.

Show id, upvotes and downvotes for each entry after the comment,
in the format (id: upvotes, downvotes).
