title: git diff with interleaved lines
body: <p>I want a diff with interleaved lines, i.e. with "hunks" no longer than one line.</p>
  
  <p>For example instead of</p>
  
  <pre><code>-t1 = "Christmas 2013"
  -t2 = "Easter 2013"
  -t3 = "Thanksgiving 2013"
  +t1 = "Christmas 2014"
  +t2 = "Easter 2014"
  +t3 = "Thanksgiving 2014"
  </code></pre>
  
  <p>I want this:</p>
  
  <pre><code>-t1 = "Christmas 2013"
  +t1 = "Christmas 2014"
  -t2 = "Easter 2013"
  +t2 = "Easter 2014"
  -t3 = "Thanksgiving 2013"
  +t3 = "Thanksgiving 2014"
  </code></pre>
  
  <p>So far I have</p>
  
  <pre><code>git diff -U0 --ignore-space-at-eol before after holidays.ini
  </code></pre>
  
  <p>I tried setting <code>--break-rewrites=0%/0%</code>, <code>--break-rewrites=100%/0%</code> and so on but it didn't change anything (I don't even know if it's relevant to my problem).</p>
