From ce301b6b0b69c98e4c711b09757345a165f25f94 Mon Sep 17 00:00:00 2001
From: Richard Levitte <levitte@openssl.org>
Date: Fri, 10 Mar 2000 12:18:28 +0000
Subject: [PATCH] Add the possibility (with -ign_eof) to ignore end of file on
 input but still not be quiet.  Also make it clear that -quiet implicitely
 means -ign_eof as well.
