Unicode prompty goodness for rbenv. This copies the unicode characters used in
rvm-prompt. I plan to add a non-unicode option eventually, but if someone wants to send a pull request I'd be happy to accept!
You can install it using Homebrew via the command below. If someone wants to contribute a Homebrew formula to the main repo that would rock.
brew install https://raw.github.com/joefiorini/homebrew/5ac0a1d8558c8a8334ce1e36114e82f6bb628e5e/Library/Formula/rbenv-prompt.rb
