title: Git Diff Returns Binary Files Differ but no actual lines
body: <p>I'm doing:</p>
  
  <pre><code>git diff HEAD -- myfle.txt 
  </code></pre>
  
  <p>and getting back: </p>
  
  <blockquote>
    <p>git diff --git a/myfile.txt b/myfile.txt 
    index ....
    Binary Files a/myfile.txt b/myfile.txt Differ</p>
  </blockquote>
  
  <p>"Binary Files Differ" .. but no print-out of the actual lines changed.  What Am I doing wrong? </p>
  
  <p>I'm also trying this between branches (i.e. git diff DEV QA -- myfile.txt) same result. </p>
