From 050cc68b402f5998193a6026d0eeeecb9d2cb9c4 Mon Sep 17 00:00:00 2001 From: Lennart Borgman Date: Wed, 11 Apr 2012 04:12:20 +0200 Subject: `narrow-to-defun' fixup * emacs-lisp/lisp.el (narrow-to-defun): `beginning-of-defun' goes to previous function when point is on the first character of a function. Take care of that in `narrow-to-defun'.
