:Yeah, I suppose we should keep the delete key as the standard delete
:and not the keypad delete. Go ahead.

Except the backarrow key still produces 0x7f on my system.

The wscons driver is in vt100 emulation mode.

On the vt100 there's a BACKSPACE key (left of the BREAK key)
which produces 0x08 and a DELETE key (below BREAK) which
produces 0x7f
On the vt220, which has a keyboard similar in layout to common PC
keyboards, the backarrow key produces 0x7f and the REMOVE key
(in the same location as the PC keyboard's DELETE key) produces
ESC [ 3 ~

So, it was set up (before the change) to be like a vt220 - even
though it was claiming to be some (extended) vt100.  Now's it's
in some weirdo hybrid mode :-)
