For the "what's up with that btw" department: A cherry-pick really is nothing but "apply the same patch as a different commit". So there is no way to say "this is already there" - because it really isn't. It's a totally different thing. In fact, it would be very wrong to filter them out, both from a fundamental design standpoint, but also from a usability/reliability standpoint: cherry-picks are by no means guaranteed to be identical to the source - like any "re-apply the patch in another place" model, the end result is not at all guaranteed to be semantically identical simply due to different bases: the patches may not even be identical, and even if they are, the results of the code may depend on what else is going on. So don't think of cherry-picks as "the same commit". It's not, and it never will be. It's a totally separate commit, they just share some superficial commonalities.
