This still doesn't work in all cases.  Typing `v' on a PDF file in Dired
activates View-mode (I type RET in Dired when the intention is to *edit*
the file, and type `v' when the intention is to *view* the file).

Doc-view-mode has no chance to disable view-mode, because view-file
(called from dired-view-file) at first visits the file with
find-file-noselect that enables doc-view-mode, and after that
view-file enables view-mode.

View-file doesn't enable view-mode only when the property `mode-class' is
`special'.  Actually lisp/doc-view.el already contains the necessary line,
but it is commented out:

;; (put 'doc-view-mode 'mode-class 'special)

I wonder what was the reason for commenting this out?
