As per the newly added restriction (User perms >= group perms >= other 
perms) is concerned, there is an inconsistency in the permission. Say for 
example, permission value is "0432". Here User has only READ permission 
whereas Group has both WRITE and EXECUTE permission and Other has WRITE 
permission. I think it is not good to give Group and Other at least WRITE 
permission whereas User itself has no WRITE permission.

May be, it's better to check those three permissions bit wise rather than as 
a whole. Please rethink about my point and let me know your opinion.

Thanks,
Gobinda
