Cannot see diff on specials characters (eg ^M)

[cscotti]

Could you provide an option which could show us if the diff is on specials characters (eg windows carriage return ^M versus unix carriage return) ?

Currently what the tool does it replace windows new lines (\r\n) for unix new lines \n and then I just split by \n.
What would you really like to see?
