The call to cmd_diff_index() "git merge-ours" makes has been working by accident that the function did not call exit(3), and the caller exited almost immediately after making a call, but it sets a bad precedent for people to cut and paste. For finding out if the index exactly matches the HEAD (or a given tree-ish), there is index_differs_from() which is exactly written for that purpose. Signed-off-by: Junio C Hamano <gitster@pobox.com>
