From c251c83df276dc0bff4d008433268ad59b7a8df2 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Sat, 6 May 2017 22:10:38 +0000 Subject: object: convert parse_object* to take struct object_id Make parse_object, parse_object_or_die, and parse_object_buffer take a pointer to struct object_id. Remove the temporary variables inserted earlier, since they are no longer necessary.
