Glad to see your response and couldn't agree more. (except maybe \e)

My response was just to show how a user who really wanted to do this
how it can be done without changing openbsd (and on their own system).
As a side note my updated solution is broke, incorrect quoting in PS1.

My question:
Having PS1 being able to run arbitrary commands is that a security risk
needing fixed?  (or if the user wants to shoot their own foot, let em!)
Low risk unless a suid program can be convinced to show a prompt.
