I expected a better reply, Sergey.  This is a copout over a huge security 
problem.  Yes, it would be nice to 'fix' the user by telling him not to do 
that, but how are you going to do that from a mailing list that is not 
subcribed to by 99.9999999% of the tar users and who will never see this 
thread?

Its tar that needs fixed, by precheckng the perms on . and refusing to touch 
. if it has no rights.  Please do the right thing.
