The problem is that lots of esc use line numbers. The first line being
the one at the top, obviously.

Terminals that implement scrollback add a line to the scrollback
buffer on \n (easy) or on esc that add lines like CSI L, CSI T, CSI
S, etc which can be tricky and sometimes plain useless in a curses
environment.

Another solution would be to write the scrollback buffer in a file,
but this can raise some security issue.
