From: Jon Seymour Date: Mon, 20 Jun 2005 02:29:38 GMT Subject: [PATCH 6/7] Prevent git-rev-list without --merge-order producing duplicates in output Message-ID: <20050620022938.28641.qmail@blackcubes.dyndns.org> If b is reachable from a, then: git-rev-list a b argument would print one of the commits twice. This patch fixes that problem. A previous problem fixed it for the --merge-order switch.
