57 | ;; Mon Nov 28 15:19:38 GMT 2005 Dave Love <fx@gnu.org> | |
58 | ;; * Abstract process startup into darcsum-start-process. Use TERM=dumb. | |
59 | ;; TERM=dumb avoids escape characters, at least, for any old darcs that | |
60 | ;; doesn't understand DARCS_DONT_COLOR & al. | |
61 | ;; | |
62 | ;; Thu Nov 24 15:20:45 GMT 2005 Dave Love <fx@gnu.org> | |
63 | ;; * darcsum-mode-related changes. | |
64 | ;; Don't call font-lock-mode (unnecessary) or use-local-map (redundant). | |
65 | ;; Use mode-class 'special. Add :group. | |
66 | ;; Add trailing-whitespace option to mode hook and fix | |
67 | ;; darcsum-display-changeset not to use trailing whitespace. | |

aa230d94 | 69 | ;;; Todo: |
5b467bf4 | 70 | |
5b467bf4 | 71 | ;; - add ability to modify a log-entry (via cvs-mode-admin ;-) |
e57a1038 | 72 | ;; - remove references to cvs-* |
aa230d94 | 73 | ;; - make it easier to add support for new backends without changing the code. |
