feature request: improve file recovery

[Ivan Kanis]

Hi,

I get from time to time a prompt saying I should recover a file. When I
do it, I find it difficult to make a decision. It would be nice
to improve the recover-file function to pop up a window that shows
difference between the current file and its recovery.

Is there interest for this feature? I might have the time to write the
feature if it will be integrated in emacs.

I can stand brute force, but brute reason is quite unbearable.  There
is something unfair about its use. It is hitting below the intellect.
