Subject: [PATCH] Utility to show a log.

This program shows commit information for a commit.

Signed-off-by: Robin Rosenberg <robin.rosenberg@dewire.com>

The main reason for this patch is not the program itself. The new code to
read really fast but doesn't always work.

Try the supplied program. I get no parents and the treeid 
is wrong. An interesting thing is that if you look in the debugger the author 
and commit messag is actually correct. Only the tree id and parent are wrong. 
Not sure what's going on. The  UnpackedReader "looks" like it does
the equivalent of what it did before,but apparently it isn't. 

Reading commits from packs works fine. It's the unpacked reader that's bad.
