title: Show git diff, ignoring file permission changes?
body: <p>I have run several <code>chmod</code> in my live server. Right now when I do a <code>git diff</code> there, I see lots of <code>old mode 100644 new mode 100755</code></p>
  
  <p>I have also changed some files there. But I would just git diff just to show the changes on the files, ignoring the file permissions changes.</p>
  
  <p>How can I do that? BTW, I don't want GIT to ignore those file permissions changes. Actually I want to commit them, I just want git diff to not show them for a very specific moment.</p>
