github throws away all the relevant information, like having even a
valid email address for the person asking me to pull. The diffstat is
also deficient and useless.
Git comes with a nice pull-request generation module, but github instead decided to replace it with their own totally inferior version. As a result, I consider github useless for these kinds of things. It's fine for *hosting*, but the pull requests and the online commit editing, are just pure garbage.
