busybox init: very limited line editing functions

[Eric Delaunay <delaunay@lix.polytechnique.fr>]

busybox does reset terminal settings via set_term() to some defaults that are
not so reasonnable:  in effect, it disables erasing characters with backspace.
Instead I get a \ displayed followed by the removed char.  For example, when I
type 3 chars then 3 backspace I get something like that displayed: abc\cba

I disabled set_term() in my local copy of busybox because boot-floppies fully
support linux terminal quite well.  Btw, TERM=linux is passed by the kernel
itself.
Erik, could only call set_term() when the TERM env variable is not set?

Regards.
