This just started happening. When you click "diff" for an entry on a recent
changes page, it compares the article's most recent edit with itself, rather
than the previous change. Another user has confirmed this. If you go into a page
history and compare two edits, that works.
Confirmed in old recentchanges view (enhanced recentchanges seems ok)
