  "message": "diff-tree: avoid lookup_unknown_object\n\nWe generally want to avoid lookup_unknown_object, because it\nresults in allocating more memory for the object than may be\nstrictly necessary.\n\nIn this case, it is used to check whether we have an\nalready-parsed object before calling parse_object, to save\nus from reading the object from disk. Using lookup_object\nwould be fine for that purpose, but we can take it a step\nfurther. Since this code was written, parse_object already\nlearned the \"check lookup_object\" optimization, so we can\nsimply call parse_object directly.\n\nSigned-off-by: Jeff King \u003cpeff@peff.net\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
