Remove a useless new line from `dig +yaml` output

Description

Currently the output of dig +yaml <domain> has an extra new line after the - for the list item, which isn't needed for it to be valid yaml. This also makes the output longer than needed. See example output:

$ dig +yaml google.com
-   <---- This newline doesn't need to be here

Request

Remove that new line. I already have a fix ready, if I could have permission to create a fork I can make a merge request.
