Bug report - git show <tagname> together with --pretty=format

Hi,
I've a problem with git 1.6.2.2 (self compiled) and git show. I use it's 
output for parsing the git data, so this is more than a minor issue for 
me. When you normally do a git show on a tag name it's output resembles 
the following:
tag <tagname>
Tagger: Cornelius <c.r1@gmx.de>
Date:   Wed Apr 8 14:39:17 2009 +0200

tagmessage commit 77e312e0527f87604e4c70ebf6040e79bb55d2ed <snip>

Now when you do a git show <tagname> --pretty=format:"ENDOFGITTAGOUTPUTMESAGEHERE%n%H" -- the Date: line is missing. Git 1.6.0.5 (which is avaible in my distro's repos) doesn't have this issue. Please CC me, I'm not subcribed here. Cornelius
