Maybe the following is a bit simpler:

       if (strbuf_read_file(&sb, git_path_abort_safety_file(), 0) >= 0) {
               int res;
               strbuf_trim(&sb);
               res = get_oid_hex(sb.buf, &expected_head);
               strbuf_release(&sb);
               if (res)
                   die(_("could not parse %s"), git_path_abort_safety_file());
       }

Thanks,
Christian.
