title: Why does git lfs migrate not track all pdf files?
body: <p><strong>Note in advance</strong>: <code>git lfs migrate import --include="*.pdf"</code> does the job as  <code>git lfs ls-files</code> shows <code>e6521dbea0 - large180m.pdf</code> (I guess). But I still don't understand what happens.</p>
  
  <hr>
  
  <p>I need to use <code>git lfs</code> and I created a test folder in <code>C:/Temp/</code> (on windows) to check whether everything is working. Unfortunatelly, it is not: <code>git lfs ls-files</code> does not list any files! See below...</p>
  
  <p>(<code>small.txt</code> and <code>small2.txt</code> are empty text files, <code>large180m.pdf</code> is a "large" pdf with 180 MB)</p>
  
  <p><strong>What is wrong here?</strong> I followed the instructions from <a href="https://github.com/git-lfs/git-lfs/wiki/Tutorial" rel="nofollow noreferrer">here</a>:</p>
