Now and then we discover that we've branched out a feature branch off of the wrong branch. To get the workflow correct, we need to move the feature branch so it branches off of the correct branch, a so called feature branch rebase.
This happens so seldom that I always have forgotten the command for how to do it, so I google it and hope for finding the same example that I found useful the last time. The example isn't hard to find, but this post is for making sure I don't lose it.
The example is copied from the section More Interesting Rebases at https://git-scm.com/book/en/v2/Git-Branching-Rebasing
