title: How to bring commits from a later branch to an earlier branch in git?
body: <p>Git newbie here, thanks in advance for the help: I've done the following:</p>
  <ol>
  <li>Create a new branch from tag v1.9 (I called it MyBranch1.9)</li>
  <li>Make some edits, commit them, and sync to the remote branch</li>
  <li>Create a new branch from an earlier tag v1.8 (called MyBranch1.8)</li>
  </ol>
  <p>I'd like to get to the following result:</p>
  <ol>
  <li>The edits I made (#2 above) end up in MyBranch1.8</li>
  <li>Edits made by others (the ones between tags v1.8 and v1.9) do NOT end up in MyBranch1.8. Effectively, I'd like to backport just the changes I made to MyBranch1.8.</li>
  </ol>
  <p>May I ask how to make Git do this? I've tried rebasing interactively but it seems to try and bring all the commits in MyBranch1.9 to MyBranch1.8.</p>
  <p>Super bonus points if you could please share the git command line syntax as I'm new to this. Thanks!</p>
