Subject: [PATCH 4/5] log: decorate grafted commits with "grafted"

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Thu, 18 Aug 2011 19:29:37 +0700

In shallow repositories, this may help detect whether a branch ends,
or it is deeper than current depth.

It also show graft points that extend a branch.
