I have trouble translating the above to what I'm familiar with in my
mind, so...

diff2:

  1
  2
  A
  <<<<<<< l
  B
  =======
  X
  >>>>>>> r
  C
  5
  6

diff3:

  1
  2
  <<<<<<< l
  A
  B
  C
  ||||||| b
  3
  4
  =======
  A
  X
  C
  >>>>>>> r
  5
  6

I personally don't mind at all having a few extra lines in order to
visualize what actually happened.

But of course there's zdiff3:

  1
  2
  A
  <<<<<<< l
  B
  ||||||| b
  3
  4
  =======
  X
  >>>>>>> r
  C
  5
  6

Which is the best of both worlds, even if not technically accurate.

Cheers.
