Fork some of your scripts to git-extras

[bric3]

Hi,

I came around your git-brv script, and quite liked it. I believe it could be promoted way more in the git-extras project which has a bigger visibility, and has already various distribution channels like homebrew (for mac users), and benefit from some integration e.g. in oh-my-zsh.

However the git-extras owner would like your permission to do so, which seems right anyway?

Issue in question tj/git-extras#770

That would be awesome if you could feed us your opinion on the matter.
Thanks a lot in advance !

Sorry for the delay. No problemo. I've commented on the other issue as well.
