[PATCH v3 0/4] Modernize read_graft_line implementation

Changes since v2:
- commit implementing free_graft dropped (no longer needed)
- several more lines moved from last commit to commit replacing
  raw buffer with strbuf
- fix for memory allocation separated from change in hash
  parsing
- commit_graft struct uses FLEX_ARRAY again, meaning free_graft,
  memset, nor oid_array were not needed after all

Patryk Obara (4):
  sha1_file: fix definition of null_sha1
  commit: replace the raw buffer with strbuf in read_graft_line
  commit: allocate array using object_id size
  commit: rewrite read_graft_line
