From a1509f53203c8d6752847160e851e0bf1ceedd7d Mon Sep 17 00:00:00 2001
From: Kenneth R Westerback <krw@cvs.openbsd.org>
Date: Wed, 2 Jul 2003 16:42:20 +0000
Subject: Eliminate cutword(), replacing it with specific code: 'set --' in two
 cases and a simple sed expression in the third.

Add pfsync to the list of interfaces that should not be offered to the
user for configuration.

Display the server line selected from the ftp/http server list in a
more compact form with only a single space between fields.

The usual [] -> [[]], etc. in areas being revised.
