bug during packing?

[Lukasz Jachowicz]

I'm not sure if it is a bug, or a feature, but

tar -c * * * * > smth.tar

gives us the destination file 4 times bigger than the source directory.
Each file is added few times. Shouldn't tar check if the file is already
tar-ed and omit it in such a situation?

It could be done by creating a small file in temp dir with names of all
already packed files... And this checking (it can slow down the process)
could be turned on as an option...

greetings,
Lukasz
