For git-multimail, there are actually a lot of false-positive due to the
way we use multiple-inheritance (when calling super(...).__init__(),
lgtm assumes we're calling the superclass's constructor while we
actually call the "next in the method resolution order list"), but also
probably valid concerns.

I've set up a separate project for git-multimail:

  https://lgtm.com/projects/g/git-multimail/git-multimail/alerts/?mode=list

I'll have a deeper look ASAP.

Thanks!
