The problem is this.  How long do you want `ls -l' take?  Checking
permissions is awkward and lengthy on Windows, unless you have the
user's token.  The access check can be improved and the permissions
more correctly shown for the current user, but for any file and any
user account, it'd be a lot of time-consuming effort.
