title: Do I need to perform a commit after a rebase?
body: <p>I've just rebased a feature branch onto another feature branch (in preparation for rebasing everything to the head of my master), and it involved quite a few tricky merge resolutions.</p>
  
  <p>Is the rebase automatically saved as a commit somewhere? </p>
  
  <p>Just where do those modifications live? I can't see anything in gitk, or <code>git log --oneline</code>.</p>
  
  <p>(Same question for when I merge back my branch after rebasing.)</p>
