Excellent ideas!  I don't have anything to add ;-)

This makes [1/2] a rather new patch though, I moved the whole
prefix/suffix handing further out to accommodate different styles.

There's a little change in [2/2] apart from the obvious option
renaming, too: it interprets --color-words and --word-diff as an
initial setting for the checkbox.


Thomas Rast (2):
  diff: add --word-diff option that generalizes --color-words
  gitk: add the equivalent of diff --color-words
