Feature Request -- Prompt on right side

[ryanmusante]

How do I add a similar right side prompt for SSH sessions as is the current GIT setup?

I want to be aware of connections to other systems in my LAN using the same visual configuration.

}

Then, put this in your prompt:

$(git_prompt_string)

Oops, I didn't read correctly. Anyway, this what the git indicator uses. Functions and case statements are your friend

[ryanmusante]

Ok, got it.
