Enhanced RC generates these "(3 changes | history)" links for every block of grouped recentchanges. That changes-link links to a diff page. For Flow, that is all wrong: we have different ids (not integers), on a different page (&curid=&oldid=&diff= means nothing). Even the concept of a "diff" page seems wrong here for us - a new post is not part of some document that can be diffed. In short: we'll want to generate a different link, and we'll need a hook to let us change them. Meanwhile also split the code that generates those links into a separate method.
