From fb1440bad5cc00c25587f3b0fd43054fcd16e25e Mon Sep 17 00:00:00 2001 From: mdodd Date: Thu, 19 Aug 1999 03:29:15 +0000 Subject: Add support for command line editing and history. Remove src/contrib/bind/bin/nslookup/commands.c as it is generated by lex from commands.l. Submitted by: lpc/cdcontrol patches originally by msmith.
