title: git clone comes with edited files
body: <p>When I clone a project, I did <code>git status</code> right away and some files appear edited.
  I check with <code>git diff .</code> and all edited files have the same message: &quot;<strong>warning: CRLF will be replaced by LF</strong>&quot;.
  I didn't even open any files.
  <code>git checkout .</code> didn't work.
  How is this possible?</p>
