right side prompt

[jceaser]

created a working left/right prompt on fish, should work for any shell (like zsh). This is my opening conversation on the topic and I'm looking for feed back. Usage is as such (for fish):

function fish_prompt
powerline-shell --shell bare $status
end

function fish_right_prompt -d "Write out the right prompt"
powerline-shell --shell bare --side right $status
end

Configuration is a bit different:
{
"left":
{
"segments": ["cwd"],
"cwd":{"max_dir_size": 1, "full_cwd":"True"},
},
"right":{"segments": ["exit_code"]}
}
