Magit workflow for contributing to oss

It's been only a little while since I made a pull request to an open-source project and I forgot the conclusion I had about setting up my local git repository.

I structure my file system with git repositories from github so that it replicates the <OWNER>/<REPO> in github.

Earlier, I nearly duplicated the repository to augustfengd/<REPO> because the repository will technically exist as as fork and I will be pushing there. No.

Instead, I should configure the local upstream repository so that pushes default there:

[remote "augustfengd"]
	url = https://github.com/augustfengd/spacemacs
	fetch = +refs/heads/*:refs/remotes/augustfengd/*
[remote]
	pushDefault = augustfengd

And I should pull with rebase.
