title: Git, read latest commit message when committing
body: <p>When I am committing, this text jumps up:</p>
  
  <pre><code>Please enter the commit message for your changes. Lines starting
   with '#' will be ignored, and an empty message aborts the commit.
  
   On branch master
   Your branch is ahead of 'origin/master' by 2 commits.
  
   Changes to be committed:
  
      new file:   modules/new_file.txt
  </code></pre>
  
  <p>What I want is to let this informative text also show me the message of my last commit, without me needing to go through <code>git log</code>, <code>git show</code> or anything similar. </p>
  
  <p>E.g.</p>
  
  <pre><code>(...)
  
   Changes to be committed:
  
      new file:   modules/new_file.txt
  
   Previous commit message:
      [FIX] Fixed the foo.bar module
  </code></pre>
  
  <p>This is exactly the same as <a href="https://stackoverflow.com/questions/7293008/git-how-to-read-last-commit-comment">this question</a>, but none of the answers was actually answering the question, so I guess OP just asked it a bit wrong? </p>
