;;; 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
