Almost all the cases I can think of where executing shell commands may
call $EDITOR, I can also think of very nice emacs libraries that provide
very mature integration.  A few examples:
- emails: Gnus, notmuch, vm, message-mode for simple composing, etc,
- using version control: vc-*, magit, etc,
- sudoedit/visudo: tramp

The only one I can think of without a mode like that is when I call
$EDITOR from my pager (less).  But of course running a pager from Emacs
does not make sense.  From the above examples, I can't imagine I would
call any of those from dired.  So I'm still a bit confused about the use
case.  Could you please give an example of the command you are using?

Sorry if I'm being a bit dense, I'm just very curious and would like to
know.

Thanks,
