Err, it's not really a bug: bterm needs to be run on the VT, otherwise
it can't do its work, i.e. draw the text itself on the linux
framebuffer.  Put another way, it has to be screen that should be run
inside bterm, rather than bterm run inside screen (which can't work).

Furthermore, please read other /lib/debian-installer.d scripts, they
do assume that they are running on the VT, for instance S40term-linux
turns off console blanking, but only if TERM is linux. Running all these
inside screen drops a lot of support...

Put another way, why stuffing the screen support in the debian-installer
script rather than in S70menu, as bterm does?
