Rework init-file migration. 2007-12-19 Mike Sperber <mike@xemacs.org> * startup.el (user-init-file-migration-in-order-p): Factored out check. (maybe-migrate-user-init-file): (migrate-user-init-file): Don't do a backup of ~/.emacs anymore. Instead, make only a manual adjustment of the file, if at all, i.e. don't go through customize magic anymore. (unmigrate-user-init-file): Don't use customize to set `load-home-init-file' anymore. (set-load-home-init-file): Add; performs the modification previously done through customize. (unmigrate-user-init-file): Use `set-load-home-init-file' instead of customize. (command-line-1): Only wait for the first event if we're not going to ask about migration.
