One minor wrinkle is that completion-auto-help has 3 valid values: nil, 
t, and lazy. I'm not sure I understand the difference between t and 
lazy, so I'm also unsure as to how to apply them to ido. In my testing, 
both t and lazy seem to result in the identical behavior in 
completing-read-default.
