title: Rename commit message after pushing to github
body: <p>I have two commits that I just pushed to github</p>
  
  <p>The 2nd commit message after the 1st commit message is actually a bit messed up.</p>
  
  <p>Is there a way to change the 2nd commit message after pushing it to github?</p>
  
  <p>I know amend will work only if it hasn't been pushed to github. No one hasn't branched off my current dev branch, so it's safe to assume that no one will be affected if I do this.</p>
