I don't think this is necessarily a git mess-up. If you pull between two
(or more) streams, you are bound to get the same commits through different
merge paths multiple times. The end result will be OK because git is smart
enough to handle it it just makes the commit graph a bit more complicated
(that's why for review it is best to look at the overall diff before/after
the merge, which is what github shows for the diff of a pull request) .
