Both sha1_file.c and packfile.c now need read_object(), so a copy of read_object() was created in packfile.c. This patch makes both mark_bad_packed_object() and has_packed_and_bad() global. Unlike most of the other patches in this series, these 2 functions need to remain global. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
