Version is 1.9.1 in 2.0.0 tarball

[gthb]

The 2.0.0 release tarball reports the wrong version:

$ curl -LO https://github.com/visionmedia/git-extras/archive/2.0.0.tar.gz
$ tar xvfz 2.0.0.tar.gz
$ git-extras-2.0.0/bin/git-extras --version
1.9.1
$ grep VERSION= git-extras-2.0.0/bin/git-extras 
VERSION="1.9.1"
