Here is an updated patch that addresses several of the points brought up so far, such as the sleep, internationalization banner, and zero wait check, and it removes the premature input check.
Unfortunately rl_clear_screen() is not included at all in libedit, causing compilation to fail, and I was completely unable to find a way to distinguish libedit from readline on OS X. It tries extraordinarily hard to pretend that it's readline. Instead falling back to simple control characters to clear the screen worked very well on both linux and OS X.
