[Rd] Why R should never move to git

[Iñaki Úcar]

For what it's worth, this is my workflow:

1. Get a fork.
2. From the master branch, create a new branch called fix-[something].
3. Put together the stuff there, commit, push and open a PR.
4. Checkout master and repeat from 2 to submit another patch.

Sometimes, I forget the step of creating the new branch and I put my
fix on top of the master branch, which complicates things a bit. But
you can always rename your fork's master and pull it again from
upstream.
