It seems that Emacs 25 prefers doc-view-mode for displaying various
contents such as application/pdf mime types. I'd prefer external viewers
as defined elsewhere in my system (mailcap). I can brutally delete every
reference to doc-view-mode from mailcap-mime-data variable (see the code
below) but I'd prefer taking a less brutal route. Any ideas?


(require 'cl-lib)
(require 'mailcap)
(setq mailcap-mime-data
      (mapcar (lambda (major)
                (cons (car major)
                      (cl-remove-if
                       (lambda (minor)
                         (cl-member-if
                          (lambda (v)
                            (cl-member v '(doc-view-mode
                                           pdf-view-mode
                                           view-mode)))
                          (cdr minor)
                          :key 'cdr))
                       (cdr major))))
              mailcap-mime-data))
