If not, perhaps there should be one. I long ago put (setq tramp-mode nil) into my ~/.emacs file because of security concerns, so I wouldn't need to selectively disable sudo myself. But perhaps others who are less concerned about security (but still somewhat concerned) might want it. Come to think of it, if 'emacs -Q' enables Tramp by default then perhaps I should stop using 'emacs -Q'....
