From 33196372bed41405ff240f13fe63ca5587912ed2 Mon Sep 17 00:00:00 2001 From: Denis Vlasenko Date: Sat, 23 Feb 2008 01:25:38 +0000 Subject: less: update line input so that it doesn't interfere with screen update. Makes "man bash", [enter], [/], , [enter] more usable - manpage draws as you enter the pattern!
