docs: Create a follow-up on a post `post`.
  
          It seems like if the post has `<p>` tags, then it's treated as HTML,
          but is treated as text otherwise. You'll want to provide `content`
          accordingly.
  
          :type  post: dict|str|int
          :param post: Either the post dict returned by another API method, or
              the `cid` field of that post.
          :type  content: str
          :param content: The content of the followup.
          :type  anonymous: bool
          :param anonymous: Whether or not to post anonymously.
          :rtype: dict
          :returns: Dictionary with information about the created follow-up.
