[PATCH] Tweak git-diff-tree -v output further.

From
Junio C Hamano <junkio@cox.net>
Date
May 6, 2005, 19:27 UTC
Message-ID
<7vd5s4cfzq.fsf@assigned-by-dhcp.cox.net>

The first hunk of this is a pure bugfix---it guards us against a commit message that does not end with a newline.

This adds the full header information to git-diff-tree -v output in addition to the log message it already produces.

Maybe we want to stop indenting so that it matches what git-export produces better.
