  "message": "merge-base: die with an error message if not passed a commit ref\n\nBefore this patch \"git merge-base\" just exited with error code 1\nand without an error message in case it was passed a ref to an\nobject that is not a commit (for example a tree).\n\nThis patch makes it \"die\" in this case with an error message.\n\nWhile at it, this patch also refactors the code to get the\ncommit reference from an argument into a new\n\"get_commit_reference\" function.\n\nSigned-off-by: Christian Couder \u003cchriscool@tuxfamily.org\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
