Comment 13 for bug 883176

I think we should work towards git-review without the need of .gitreview file at all. There is a work underway (https://review.openstack.org/#change,5720) to not need .gitreview at all to determine repository access and derive it fully from existing git remotes as well as using any remote (https://review.openstack.org/#change,5784) instead of hardcoded "gerrit".

I think it is also possible to get branch name out of gerrit metadata (at least when subsequent changes are submitted, but for the first change it might probably be derived from HEAD).
