Patch Set 1: Code-Review+1

Gah. I spent time scratching my head how dirs are handled by muntar then realized there is already #259 for that (hint hint, if you want jperkin). :)

Code looks good to me and works with the couple tars I tried.

How do we decide we are comfortable enough to release this? tar-stream has some tests at least.
