From 26cdce2387403f2b7a3eaf2b40fe72fc903b4a0e Mon Sep 17 00:00:00 2001 From: Juri Linkov Date: Wed, 15 Aug 2007 23:24:17 +0000 Subject: [PATCH] (initialization): Change parent group from `internal' to `environment'. (initial-buffer-choice): New variable. (command-line): Revert 2007-07-02 change that sets buffer-offer-save in *scratch* and enables auto-save in it. (fancy-splash-text): Add links to existing items. Add new items with links for useful tasks. Move information about Control-g to fancy-splash-head. Move "Emacs Guided Tour" to the end. (fancy-splash-keymap): New variable. (fancy-splash-last-input-event): Remove variable. (fancy-splash-insert): Add processing of `:link' element. (fancy-splash-head): Replace "Type Control-l to begin editing" with "Type `q' to exit". (fancy-splash-screens-1): Let-bind inhibit-read-only to t. (fancy-splash-default-action, fancy-splash-special-event-action): Remove functions. (fancy-splash-quit): New function. (fancy-splash-screens): Rename input arg from `hide-on-input' to `static' and reverse the condition of its usage. Don't preserve original values of `minor-mode-map-alist', `emulation-mode-map-alists', `special-event-map'. Rename startup-buffer from "*About GNU Emacs*" to " GNU Emacs". Rename about-buffer from " GNU Emacs" to " About GNU Emacs". Remove processing of special events. Use local key map `fancy-splash-keymap'. Set buffer to read-only. (normal-splash-screen): Rename input arg from `hide-on-input' to `static' and reverse the condition of its usage. Rename startup-buffer from "*About GNU Emacs*" to " GNU Emacs". Rename about-buffer from " GNU Emacs" to " About GNU Emacs". Add links to existing items. Add new items with links for useful tasks. Use local key map `fancy-splash-keymap'. (display-splash-screen): Rename input arg from `hide-on-input' to `static'. (about-emacs): Add alias to display-splash-screen.
