Re: [PATCH 5/5] commit: rewrite read_graft_line

> The previous implementation of read_graft_line used calculations based
> on GIT_SHA1_RAWSZ and GIT_SHA1_HEXSZ to determine the number of commit
> ids in a single graft line.  New implementation does not depend on these
> constants, so it adapts to any object_id buffer size.
>
> To make this possible, FLEX_ARRAY of object_id in struct was replaced
> by an oid_array.
>
> Code allocating graft now needs to use memset to zero the memory before
> use to start with oid_array in a consistent state.
>
> Updates free_graft function implemented in the previous patch to
> properly cleanup an oid_array storing parents.
