From 67991cf824f8df27e74c92d754fb507681c69ce6 Mon Sep 17 00:00:00 2001
From: Eric Andersen
Date: Wed, 14 Feb 2001 21:23:06 +0000
Subject: This patch, put together by Manuel Novoa III, is a merge of work done
 by Evin Robertson (bug#1105) and work from Manuel to make usage messages
 occupy less space and simplify how usage messages are displayed.
