From eec89a90ffdd077d687914fe18a9e48028f07fb4 Mon Sep 17 00:00:00 2001 From: Thomas Martitz Date: Fri, 20 Dec 2013 23:34:28 +0100 Subject: lists: Adapt put_line(). This enables removing large portions of code, simplifiyng the drawing routine. All of the removed code is functionaltiy now available through put_line().
