[erlang-questions] erl_tar improvements

[Max Lapshin]

I have met another problem with recursive directories.

I've written a tool that creates debian packages and wanted to use
erl_tar. dpkg requires that directories must exist in tar archive and
erl_tar cannot add only directory, it starts adding files inside and
forget to add inner directories.
So, this archive becomes unuseable for dpkg.

I think that I need to make a patch and try to push it to mainline.
