Use gitk and switch into "Markup words" or "Color words" mode (e.g.
"gitk --color-words -- bug.txt"), and then select one of the radio
buttons. You will see:

  * "Diff" shows bogus removal on 1st line and bogus addition on 2nd line.
  * "Old version" cuts off at right angle bracket.
  * "New Version" cuts off at left angle bracket.
