82 | ;; Thu Nov 24 15:20:45 GMT 2005 Dave Love <fx@gnu.org> | |
83 | ;; * darcsum-mode-related changes. | |
84 | ;; Don't call font-lock-mode (unnecessary) or use-local-map (redundant). | |
85 | ;; Use mode-class 'special. Add :group. | |
86 | ;; Add trailing-whitespace option to mode hook and fix | |
87 | ;; darcsum-display-changeset not to use trailing whitespace. | |
