Most of the callers of this function except only one pass NULL to its last parameter, ignore_packed. Introduce has_sha1_kept_pack() function that has the function signature and the semantics of this function, and convert the sole caller that does not pass NULL to call this new function. All other callers and has_sha1_pack() lose the ignore_packed parameter. Signed-off-by: Junio C Hamano <gitster@pobox.com>
