Thanks Stefan. I changed the copyright.

Here is a rewritten introduction for those unfamiliar with vimdiff.

vdiff compares two or three buffers on the basis of the output from
the diff tool. The buffers are kept synchronized so that as you move
through one of the buffers the top of the active buffer aligns with
the corresponding top of the other buffer(s). This is similar to how
ediff works, but in ediff you use a third “control buffer” to move
through the diffed buffers. The key difference is that in vdiff you
are meant to actively edit one of the buffers and the display will
update automatically for the other buffer. Similar to ediff, vdiff
provides commands to “send” and “receive” hunks from one buffer to the
other as well as commands to traverse the diff hunks, which are useful
if you are trying to merge changes. In contrast to ediff, vdiff also
provides folding capabilities to fold sections of the buffers that
don’t contain changes. This folding occurs automatically. Finally, you
are encouraged to bind a key to `vdiff-hydra/body’, which will use
hydra.el (in ELPA) to create a convenient transient keymap containing
most of the useful vdiff commands.

This functionality is all inspired by (but not equivalent to) the
vimdiff tool from vim.
