title: git recursive strategy with multiple ancestors and kdiff3
body: <p>I'm running a merge with a scenario where several "common ancestors" are available so Git runs "git merge recursive" strategy.</p>
  
  <p>As such, it runs a merge to create a new ancestor that will, in turn, be used as CA for the contributors I'm working on.</p>
  
  <p>Ok, the problem is the following, there's a file with a conflict which "ancestor" comes from the "recursive merge" performed internally by Git, so, when I try to fix the conflict with git mergetool using KDiff3, I see the following:<img src="https://i.stack.imgur.com/Jc7le.png" alt="enter image description here"></p>
  
  <p>Is this normal? My example is a little bit "too simple" (only one line in the file, so not real), but... will having this common ancestor help?</p>
  
  <p>Thanks!!</p>
