Name the author ahead of the feed on issue index lines

Every list of articles now reads "Author · Feed · Publication · N min":
the signed-in issue page, the public issue page, the RSS feed and the
EPUB's In This Issue page. `author_label` drops an author that is empty
or only repeats the feed's title, as a dozen personal blogs do. Article
pages keep their own byline.
