Yeah, or I could just rely on the fact that lookup_commit_or_die()
already parses the commit, with something like this:

      if (get_sha1(old_ref, old) < 0)
              die(_("Not a valid object name: '%s'"), old_ref);

      /* parse the commit buffer to make sure the commit is not corrupt */
      commit = lookup_commit_or_die(old, old_ref);

      /* find existing parents */
      parent_start = buf.buf;
      parent_start += 46; /* "tree " + "hex sha1" + "\n" */
      parent_end = parent_start;

This last part should be:

        /* find existing parents */
        strbuf_addstr(&buf, commit->buffer);
        parent_start = buf.buf;
        parent_start += 46; /* "tree " + "hex sha1" + "\n" */
        parent_end = parent_start;
...

I will send an updated patch series soon.
