How to set rbenv shims for Fish shell

It is pretty easy to setup rbenv for the Bash shell as described here.

To be able to use rbenv, Ruby and its other tools from the Fish shell, a similar set of commands need to added to ~/.config/fish/config.fish:

set PATH $HOME/.rbenv/bin $PATH
set PATH $HOME/.rbenv/shims $PATH
rbenv rehash >/dev/null ^&1

Tried with: rbenv 0.4.0, Fish 2.0.0 and Ubuntu 14.04
