Before ncurses update emcas tramp mode got next echo string

_echo^H ^H^H ^H^H ^H^H ^H^H ^Hstty

after ncurses update echo string is different:

_echo^M#$ _ech ^H^M#$ _ec ^H^M#$ _e ^H^M#$ _ ^H^M#$  ^Hstty icanon erase ^H cols 32767_echo

i.e. ncurses on `dumb` terminal still do refresh all line, from begin
of string, include prompt. This is complety break emacs tramp mode to
FreeBSD host.

Is this posible to fix this?
