title: How to get 3-way merge in GIT on non-conflict merges?
body: <p>How to disable auto-merging in <strong>GIT</strong>?</p>
  
  <p>The purpose is to have the same behaviour as for conflict merges resolution in automatic merges during invocation of command chain:</p>
  
  <pre><code>$ git fetch
  $ git merge some_branch
  $ git mergetool
  </code></pre>
  
  <p>The last command leads us to 3-way merge of files in case of merge conflicts. I would like to have an easy way of performing the same 3-way merge on files without conflict merges.</p>
  
  <p>I couldn't find any solution on the internet, is there any? </p>
  
  <p>I've some workarounds in mind, but it would prefer to avoid it.</p>
  
  <p>Thanks in advance,</p>
  
  <p>Aleks</p>
