I have minor edits turned off in Recent Changes.
The bug is this:
Suppose I see a page which has had one edit made to it. I click the "diff" link -- but what I see is the diff for a more recent minor edit, which was not listed in RC.
What I *should* see is either: a) the diffs of both edits, the major and the subsequent minor. b) the diff showing what the major edit added -- ie the "last" of the major edit. Of course, this leaves me in the dark about the more recent edit, and is somewhat misleading. this option is therefore less preferable IMO
