Too tired to try it and port if necessary yet, but I'd like to ask: does it work on ZSH?

I've never used ZSH, so I don't know.

My instinct says that if you'd run into any problems, it would be with this line:

  PROMPT_COMMAND="run_on_prompt_command"

Maybe ZSH has a different API? Again though, I've always just used bash, so you'd have to try it and see.
