Running 'emacs -nw' in screen and typing stuff and then using backspace
acts as though I've pressed control-H. vi is fine.
This only seems to happen with TERM=xterm.
It also happens with TERM=linux, on the console.
But with TERM=ansi, it doesn't happen.
There are some nasty, nasty issues with screen's translation, and its occasional
refusal to do so.
However, that said, screen thinks that backspace == ^H, and it will try to
translate to get to this point.
It is in the man pages.
This is not something that I can fix, as it is (somewhat) documented behaviour.
the backspace -> ^H translation is in the man page,
and also int the screen termcap entry, but NOT in the actual
screen code !
Recently ( a recent redhat screen package ) a line was added
in /etc/screenrc to fix this.
( the line is : bindkey -k kb stuff ^H )
