./dired-aux.el:558:(declare-function mailcap-file-default-commands "mailcap" (files))
./dired-aux.el:562:This function is used to add all related commands retrieved by `mailcap'
./dired-aux.el:565: (let ((commands (and (boundp 'files) (require 'mailcap nil t)
./dired-aux.el:566: (mailcap-file-default-commands files))))
./simple.el:2743:(declare-function mailcap-file-default-commands "mailcap" (files))
./simple.el:2748:This function is used to add all related commands retrieved by `mailcap'
./simple.el:2754: (commands (and filename (require 'mailcap nil t)
./simple.el:2755: (mailcap-file-default-commands (list filename)))))
We could leave the original list intact, and add xdg-open/w32-shell-execute
to the top of the list, so it would be the first suggestion that the user
will get after the first M-n.
There is a good example how to check its availability in
`browse-url-can-use-xdg-open' that could be moved
to a more general file like simple.el.
