Subject: Back out my previous kludge to make tar files with short trailers work in
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=d22c2939d3696d743853db89f08f7ad8caf48f73;p=openbsd

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.
