Adam Vandenberg 8a60d852b3 Check git repos for validity before updating.
If you `brew install erlang` and then control-C during the git clone,
you can leave your cloned repo in an invalid state.

This change does a "git status" on the clone if it exists, and nukes
it if the status is invalid (forcing a clean clone.)
