If you import readline, then any following uses of
raw_input() will automatically use readline. You may want to
swap out the history when you use get_string() or confirm() so
they don't mess up the regular Cmd history, but the basic
functionality should work out-of-box.
I didn't realize raw_input() was so nicely overloaded. After
about 30 minutes of fighting with various bits of code (and
learning that pdb's readline doesn't save/restore history), I
tweaked up some "save the history; restore the history" wrapper
which worked well.

to hit<enter>, making it feel more uniform),
I actually have a preference for needing to press enter for
Y/N answers, too. It's distinctly *less* uniform to have some
questions requiring an enter and some not. It can be
unpleasantly surprising to the user, too.
After playing with it, allowing for a default Y/N value seems to
make it a one-key selection via <enter>, but allow for
less-surprising behavior as you detail.
Thanks for your input (no pun intended),
