This looks exactly like the ACL created by -0.3.  It produces this MASK
value.  The rest is just the logical consequence.  But it doesn't do
that for me:

  $ uname -a
  CYGWIN_NT-6.3 vmbert8164 2.0.0(0.287/5/3) 2015-04-14 10:47 x86_64 Cygwin
  $ touch alfa
  $ getfacl alfa
  # file: alfa
  # owner: corinna
  # group: vinschen
  user::rw-
  group::r--
  other:r--

  $ chmod 460 alfa
  $ getfacl alfa
  # file: alfa
  # owner: corinna
  # group: vinschen
  user::r--
  group::rw-
  other:---

  $ icacls alfa | cat
  alfa NULL SID:(DENY)(Rc,S)
       VINSCHEN\corinna:(DENY)(S,WD,AD,WEA,DC)
       VINSCHEN\corinna:(R,D,WDAC,WO,WA)
       VINSCHEN\vinschen:(R,W)
       Everyone:(Rc,S,RA)
=20
The only reason I can think of is that the parent dir has default
permissions which imply the mask value already.  So, what does
`icacls . | cat' in this directory print?
