dired-diff prompts with
Diff p with (default !home!jidanni!org!debconf!p.~8~): ~/org/debconf/ #WRONG
Diff p with (default ~/.backups/!home!jidanni!org!debconf!p.~8~): ~/org/debconf/ #Correct
when in .emacs the user does
(setq
auto-save-list-file-prefix "~/.backups/.saves-";less clutter in $HOME
backup-directory-alist '((".*" . "~/.backups/"))
backup-by-copying-when-linked t ;don't destroy other hard links
backup-by-copying-when-mismatch t)
It correctly detects that we are already at version ~8~ in that faraway
directory, but then it forgets to add the prefix to the default.
It then prompts with a non-existent wrong file doomed to fail if the
user hits RET.
Also using M-n, M-p do not make the default that it shows available to
the user to edit.
In fact the total correct prompt should probably look like one of
Diff p with (default ~/.backups/!home!jidanni!org!debconf!p.~8~): ~/.backups/
Diff p with (default ~/.backups/!home!jidanni!org!debconf!p.~8~): ~/.backups/!home!jidanni!org!debconf!p.~8~
Diff p with: ~/.backups/!home!jidanni!org!debconf!p.~8~
The idea being that the user can easily change
Diff p with: ~/.backups/!home!jidanni!org!debconf!p.~8~ to
Diff p with: ~/.backups/!home!jidanni!org!debconf!p.~7~ etc.
emacs-version "25.2.2" and I do recall I reported something similar
years ago...

I believe this bug is already fixed in Emacs 26, please try the latest
pretest.

Because M-n and M-p show possible directories where that other file
could live, not only possible backup file names. Dired-diff is not
necessarily for comparison with the backup file, it's more general.

If you are willing to make such remarks, please always make a point of
trying the latest codebase first.
