It looks like ob-shell sets up sessions just by calling `shell`, which means 
all the user's customizations for shell-mode are automatically applied. This 
includes setting the prompt (e.g., from .emacs.d/init_bash.sh), as well as the 
value of `comint-prompt-regexp`.

I can't see any straightforward way to modify ob-shell sessions without also 
changing regular shell-mode. So I wonder if the easiest way to address this 
would be to create a new mode derived from shell-mode, ('ob-shell-mode')? That 
would give us a way to modify the prompt code inside babel without interfering 
with shell-mode.

If that sounds sensible I can put together a patch for ob-shell.el. Let me know 
what you think.
