From 17a07e2ae2de36cadfac2349189e0c65e1c08d07 Mon Sep 17 00:00:00 2001 From: David Kastrup Date: Sat, 28 May 2016 11:13:53 +0200 Subject: blame: require 0 context lines while finding moved lines with -M The core part of git blame -M required 1 context line, but there is no rationale to be found in the code; it causes artifacts like discussed in the thread: . sheds some more light on the history of the previous choice.
