/**
 * Patch: disable automatic microsub/blogroll subscription on bookmark-of posts.
 *
 * By default, creating a Micropub bookmark-of post triggers a hook that
 * discovers the bookmarked URL's feed, subscribes to it in microsub, and
 * adds it to the blogroll. This patch disables that behavior entirely.
