Prompts for the second file: I bet you are thinking about the = command, not
ESC =
Even with C-u ESC = all one is given to modify is "-c"
I bet you think my backup files are right there handy in the same
dir., however, I (require 'backup-dir)
When I hit ESC = I see
cd ~/analog/
diff -c /home/jidanni/.backups/analog.cfg\!\!\!home\!jidanni\!analog\!.\~24\~
/home/jidanni/analog/analog.cfg
I don't see any feature in emacs that is going to help me from telling
emacs by hand the whole path of ....~23~, in case I want to diff with
it instead of the latest, even though emacs knows where the latest,
24, is.

OK, then how about ESC 23 ESC = do the diff with backup #23
Or maybe one should diff 23 with 24, not with the current version.
