My god, that's tons and tons of lisp to add to one's .emacs file, just
to say "I wish to have emacs still call xpdf when encountering a .pdf
file, like back before they introduced doc-view".

I'm filing an emacs-pretest-bug so they will make it easier to allow one
to choose if one wants doc-view, or stick with xpdf.

One line solution:

(setq auto-mode-alist (rassq-delete-all 'doc-view-mode auto-mode-alist))

I wonder if it is better not to include doc-view-mode in
auto-mode-alist. Personally, I can't think of an occasion that I would
like doc-view mode to view my pdf files except, perhaps, to brag about
Emacs's capability.

I have this in .emacs for a while.

  (defalias 'doc-view-mode 'ignore)

OK, but what else are needed to make
v and browse-url-of-dired-file in dired to invoke xpdf on the file,
and emacs-w3m call xpdf on http://...pdf and file:///...pdf?

Is it really a solution?  The OP's problem seems to be that he wants
xpdf to be run, but the above will only replace doc-view-mode with
fundamental-mode, right?

Is it really better to show the actual underlying PDF file's code in
fundamental-mode?  If you don't want to view PDF files in Emacs, than
don't open them in Emacs.

IMO, there should be some command in dired to open a file with an
external program.  The `!' command is not appropriate here, cause it
blocks emacs till the command finishes.  I have this code in my .emacs
for that (and bound it to `e' in dired-mode-map):

--8<---------------cut here---------------start------------->8---
(defun th-dired-find-file-externally (arg)
  "Open file or directory with an external application.
If ARG is given use `xdg-open', else query for an app."
  (interactive "P")
  (let ((file (dired-get-file-for-visit)))
    (start-process "dired-external"
                   nil
                   (if arg
                       "xdg-open"
                     (completing-read "Command: "
                                      th-external-command-list))
                   file)))
--8<---------------cut here---------------end--------------->8---

th-external-command-list is a list of all executables in PATH, which I
use in several places.  I think that could be taken out.  A default
value with the appropriate external app taken from mailcap could be
used instead.

There are occasions were editing a PDF in a text editor is needed.
Emacs should not make that difficult to do.

But there is, it's bound to "&".

Wow, how could I miss that?  It's not in the "Operate" menu, but it
definitively should!

Dired is one of the few modes where I rely on the menu bar.

The command find-file-literally is for such situations.

And `C-c C-c' in doc-view will switch to fundamental-mode, too.  With
another `C-c C-c' you can jump back to doc-view and directly view the
changes you made.

You don't even need that: as the message in the echo-area explains, you
can simply hit C-c C-c to toggle between viewing the document or viewing
the underlying PDF code.
