[Mlterm-dev-en] mlterm 3.8.8 clears perhaps too aggressively

[Yuri D'E. <wa...@th...>]

Compared to previous versions, mlterm 3.8.8 has a different shrinking
behavior.

I often keep the terminal maximized, and when switching a terminal
between two screens (which are not the same size) I often now stare at a
completely blank terminal. If you had a command running which does't
emit any output, there's no feedback of what is going on.

It seems that the window content is put in the backscroll, which is
helpful as it doesn't get trimmed when the window is resized, but then
it's moved away.

Maybe just showing the backscroll until some new output is shown would
improve the behavior. But clearing the window because we lost a visible
column is excessive. I'd rather have the previous behavior where the
column was simply truncated.
