(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. diff -r ec1103d2c1c7f17396af875d6831bb049c8c0356 -r 6b571dc4ba3fe8413c178b8f1bba807925ffddf3 lisp/ChangeLog --- a/lisp/ChangeLog Fri Dec 21 03:39:10 2007 -0800 +++ b/lisp/ChangeLog Fri Dec 21 16:51:30 2007 +0100 ＠＠ -3,6 +3,23 ＠＠ 2007-12-18 Mike Sperber <mike(a)xemacs.o * autoload.el (process-one-lisp-autoload): Insert <immediate> into the section header for immediate autoloads, to make sure the upstream doesn't think there aren't any autoloads at all. + +2007-12-19 Mike Sperber <mike(a)xemacs.org&gt; + + * startup.el (ask-about-user-init-file-migration-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. 2007-12-18 Aidan Kehoe <kehoea(a)parhasard.net&gt; diff -r ec1103d2c1c7f17396af875d6831bb049c8c0356 -r 6b571dc4ba3fe8413c178b8f1bba807925ffddf3 lisp/startup.el --- a/lisp/startup.el Fri Dec 21 03:39:10 2007 -0800 +++ b/lisp/startup.el Fri Dec 21 16:51:30 2007 +0100 ＠＠ -849,12 +849,16 ＠＠ the menubar)."
