Thanks for the suggestion.
The part I'm not sure about regarding `diff-no-select' &
`diff-buffer-with-file' is how they could work with version-control
(vc-diff or a related functions).
As far as I can see the diff needs to be generated by version-control
(git/hg/svn etc) instead of a file - since the "original" file
necessarily exist as a file on disk.
