From 0053e902b4f777ba454b62263d3695e5292b1559 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 13 Mar 2007 01:57:22 -0700 Subject: [PATCH] git-log --first-parent: show only the first parent log If your development history does not have fast-forward merges, i.e. the "first parent" of commits in your history are special than other parents, this option gives a better overview of the evolution of a particular branch.
