For emacs (not a fan of K&R style, but this should keep me on straight and narrow), add .dir-locals.el to the project directory, containing:

;;; Directory Local Variables            -*- no-byte-compile: t -*-
;;; For more information see (info "(emacs) Directory Variables")

((nil . ((c-basic-offset . 4)
	 (c-default-style . "k&r"))))
