title: How can I diff 2 files while ignoring leading white space
body: <p>I have 2 source files, they are different versions of the same thing. However, one has been through a different editor that made indent changes, so all the lines are showing up different in diff.</p>
  
  <p>Is there a diff command or a filter I can use to diff with so that the output will only be lines that are different after ignoring the leading spaces/tabs?</p>
