From d22c2939d3696d743853db89f08f7ad8caf48f73 Mon Sep 17 00:00:00 2001
From: millert <millert@openbsd.org>
Date: Tue, 25 Mar 1997 09:30:19 +0000
Subject: [PATCH] Back out my previous kludge to make tar files with short
 trailers work in favor of a simpler change--never try to do a media change
 when invoked as tar.  This fixes problems that crop up if gzip exits
 unhappily and others.
