Subject: [PATCH 2/4] builtin/blame: dim uninteresting metadata
Date: Thu, 9 Nov 2017 17:10:00 -0800 [thread overview]
Message-ID: <20171110011002.10179-3-sbeller@google.com> (raw)
In-Reply-To: <20171110011002.10179-1-sbeller@google.com>
When using git-blame lots of lines contain redundant information, for
example in hunks that consist of multiple lines, the metadata (commit
name, author, date) are repeated. A reader may not be interested in those,
so offer an option to color the information that is repeated from the
previous line differently.
