A GNU tar bug that is known since 1994 (this is when I reported it
to the maintainer).

GNU tar is not POSIX compliant and it seems that nobody cares that fact.

I stopped reporting bugs for GNU tar in 1995 (there are many) when I found
that none of the bugs get fixed. As you see, it would have wasted my time.
Now, 9b years later the bugs still have not been fixed.

Conclusion: do not use GNU tar.

Would you ever trust an archiver program that behaves differently in 
list/diff/extract mode?
