I wouldn't bother if I were you: that code is a horrible mess, and the
re-work that we're doing right now will clean a lot of that up.  The
old code has coupling all over the map for prompt handling, and we're
trying to clean that as well.  If you're really curious, the code is
in core/prompts.py, and the object in the main ipython that handles it
is get_ipython().outputcache.  So grepping around for that guy may
help, but as I said, I'd let it go for now and live with using
exec_files, until we finish up the housecleaning :)

Cheers,
