The worst thing that can happen is that you reveal some garbage
when you increase size of your terminal, because program tried to clear
it when it was hidden.

I clear it even if it is hidden now with the second version of the
patch. For example when character is deleted and all characters after it
are shifted, invisible characters are just lost.

Glitches that happen when you type a long string at sh prompt and shrink
terminal are not worse, they are just different now.

I can live without scrollback, but what I dislike about st now is
that it loses lines when I just shuffle my terminals around with
dwm. When I have 3 windows (1 master, 2 stack) and move terminal
to stack and then back, half of the lines are lost. With scrollback,
it is stateless: what terminal displays depends only on the layout of
windows you end up with, not the history.
