commit 3eeb823f92c911f2427012786527c51430f057dc
parent 2921be2f38888825ff0c7373aadc25f963c0ba2e
Author: David Lawrence Ramsey <pooka109@gmail.com>
Date: Mon, 31 Jan 2005 18:59:30 +0000
add multibyte character support to indent_length(), convert the "smart
home" routines to use it (since it returns the number of bytes taken up
by spacing characters at the beginning of the line), and rearrange a few
initializations near asserts
