From 813b4734fcb82e541658b33b8563387c197d6247 Mon Sep 17 00:00:00 2001 From: Johannes Sixt Date: Fri, 8 Jun 2007 23:28:39 +0200 Subject: [PATCH] filter-branch: Simplify parent computation. We can use git rev-list --parents when we list the commits to rewrite. It is not necessary to run git rev-list --parents for each commit in the loop.
