I think the best you can do in Vim is to set the number of
context lines to zero, and fold all unchanged lines.

:set diffopt?
:set diffopt=filler,context:0

Some normal mode commands are useful:

za toggle current fold open/close
zR reveal all (open all folds)
zM minimise all (close all folds)

Using Beyond Compare can provide some benefits because you can
use it to show only the diffs, then select-all and copy only the
different lines. I haven't found a way to do that in Vim.
