     The ACL info is also used to check if a file is read-only (when opening the

! 						*read-only-share*
! When MS-Windows shares a drive on the network it can be marked as read-only.
! This means that even if the file read-only attribute is absent, and the ACL
! settings on NT network shared drives allow writing to the file, you can still
! not write to the file.  Vim on Win32 platforms will detect read-only network
! drives and will mark the file as read-only.  You will not be able to override
! it with |:write|.
