title: With git, how to save/pause a ongoing big rebase to do something else, then go back to it?
body: <p>So I have started to rebase a big branch on my current master (75 commits). I know it will take me a day or so. In the meantime, I need to address some comments on another PR. </p>
  
  <p>How can I suspend my current rebase to amend my PR without re-cloning the repo or copying the folder (these would work of course)? Is this even possible?</p>
