;;; Commentary:

;; A smart editing mode for m4 macro definitions.  It seems to have most of the
;; syntax right (sexp motion commands work, but function motion commands don't).
;; It also sets the font-lock syntax stuff for colorization

;; To Do's:

;; * want to make m4-m4-(buffer|region) look sorta like M-x compile look&feel ?
;; * sexp motion commands don't seem to work right

;;; Thanks:
;;;         to Akim Demaille and Terry Jones for the bug reports
;;;         to Simon Marshall for the regexp tip
;;;         to Martin Buchholz for some general fixes
