Please install it. The first part of the patch is installed now. But I still see no unanimous consensus on what command to bind to TAB in read-expression-map. Currently it inserts just a tab character, and this is useless in the minibuffer. I think we could add a new command `lisp-indent-or-complete' that will complete a Lisp symbol if the character preceding point is symbol-constituent, or indent line or region otherwise. And bind TAB in read-expression-map to this command. Note that I don't propose to bind TAB in emacs-lisp-mode to this command by default. So no changes in emacs-lisp-mode (though it will be available to easily rebind TAB in .emacs to everyone who likes this behavior). -- Juri Linkov http://www.jurta.org/emacs/
