  49
  50         * sec_acl.cc (search_ace): Use id == -1, instead of < 0, as wildcard.

  61         Preserve all inheritances through chmod and chown calls. Introduce
  62         isownergroup to implement the uid == gid case, to keep the inheritance
  63         code simple. Do not initialize owner_sid and group_sid and stop using
  64         the variable psd.
