It's easier if I write a user story here.
I want to use the recent changes feed to replace
getting wiki changes by email.
If a page called FooBar gets updated twice, I would get
two email messages, with summaries of the changes.
However, in a recent changes feed I only get one item
called FooBar that has a link URL that points to the
last FooBar diff page. I effectively miss the
information about the first edit to the page altogether.
It would be much more useful if there was an item in
the feed for each page edit for FooBar, with the link
pointing to the specific individual diff page for that
