To aid the effort, extract a new function, check_old_oid(), and use it in the two places where the read value of the reference has to be checked against update->old_sha1. Update tests to reflect the improvements. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
