Fixed in git, commit cbbfebbc.

(Note that any rebinding of ^H on a terminal emulator on the BSDs or macOS will still only work when --raw/-K is used.)

Hm.  The "translating" of ^H to Bsp on Apple and FreeBSD and NetBSD does not have the intended effect.  I've just now run nan-4.8 on a real NomadBSD console and Sakura terminal emulator.  On the console, there is no point in trying to rebind ^H, because it would rebind <Backspace> too, and I cannot imagine people really wanting that.  And on a terminal emulator, it would be perfectly possible to rebind ^H separately from <Backspace> (when using --raw/-K), but the "translation" code prevents that, causing in fact the opposite rebinding to occur: <Backspace> is rebound, and ^H continues deleting to the left.

In short: the translating of ^H to Bsp on FreeBSD and NetBSD and Apple is no good.  Also, trying to make allowances for the BSD consoles does not have much value: selecting text while holding Shift does not work there either, nor do Ctrl+arrow.

"""I am binding ^H to `replace all`. This has the unexpected result that pressing Backspace enters the replace menu. I know that on some terminals Backspace generates ^H, but if I use the shortcut for `Verbatim Input` and press Backspace, I get `^?`."""
