This looks complicated. The list of changes I see in the editor doesn't
exactly match the changes which would have to be removed from master,
I'm not comfortable enough with git to be sure this will result in the
right state, especially since it seems to change the remote immediately.

Duh. I was hoping to avoid reverts.
So, three strategies now. Which one is the best? I saw the renaming
strategy on the net and it seemed to be the one with the least hassle...
