.hg directory should be absent in tarballs. It contains some useless junk. release.py should ensure that unversioned files/directories are not included in tarballs.

To accomplish this need on other projects, I use hgtools as a file finder plugin. I don't want to integrate it with setuptools because of the complications around setup_requires (and the bugs that result). We could bundle hgtools and invoke it in release.py.

I see the files you're referencing in the setuptools 0.8b2 release. I'm not even sure how those files get included.

I just re-ran the sdist command on the default tip and those files don't get included, so I expect they'll be absent in the next release.

Confirmed the 0.8b3 release doesn't include the .hg directory.
