True, because someone might want to use a completely different key for VERASE. The case I had in mind though was the user setting 'stty erase ^H', to get ^H as the backspace keycode, but then finding that it would send ^? again when in screen, even though 'stty -a' would still show ^H.

Nice. The patch looks good to me, and I agree DECBKM is a better solution than a CYGWIN option, because it's standard and because it can be used in remote scripts.
