tar problem - symlinked file

[Jong B. Lee]

tar does not teat well symlinked file
when it is symlinked to a file in its parent directory.

Here's the case.
Current directory is <test> and a file, <foo>, is in the parent directory.
$ ls -s ../foo foo
$ cd ..

$ tar cvf test.tar test
$ rm -rf test
$ tar xvf test.tar
$ cd test
$ls -laF
Wow!
The size of foo is zero !
