;; * want to make m4-m4-(buffer|region) look sorta like M-x compile look&feel ?
;; * sexp motion commands don't seem to work right
-;; to autoload m4 lisp code:
-;; (autoload 'm4-mode "m4-mode" nil t)
-;;
-;; or can use (load "m4-mode") or (require 'm4-mode) to just load it
-;;
-;; to try to "auto-detect" m4 files:
-;; (setq auto-mode-alist
-;; (cons '(".*\\.m4$" . m4-mode)
-;; auto-mode-alist))

;;; to Akim Demaille and Terry Jones for the bug reports
