--- Comment #4 from Kunal Mehta (Legoktm) legoktm.wikipedia@gmail.com --- Assigned before somebody certainly steals this issue to me. I am going to add a modified difflib version. Unless the lack of feature is fixed in recent Python builds or, of course, anyone makes an objection. I am not sure about a config option to enable or disable line-by-line/char-by-char comparision.
