Access is controlled by ACLs that may have more entries than just for owner,
group and everyone. "ls -l" displays a "+" when this is the case.
You can observe the acl with "getfacl" or "cacls".
chmod does not affect the permissions of the extraneous groups, but you can
change or remove them with "setfacl" or the Windows security GUI.
If you use setfacl on a directory, I highly recommend that you specify default
permissions for owner, group and everyone. Otherwise files created by non-cygwin
applications may have unexpected permissions.
