Subject: [PATCHv3 3/4] builtin/blame: add option to color metadata fields separately
Date: Thu, 4 Jan 2018 14:40:06 -0800 [thread overview]
Message-ID: <20180104224007.214548-4-sbeller@google.com> (raw)
In-Reply-To: <20180104224007.214548-1-sbeller@google.com>
Unlike the previous commit, this dims colors for each
metadata field individually.
