Wow. It's hard getting the screen handling stuff working correctly when
|
||||
there is a screen buffer larger than screen size and vice versa. These
|
||||
changes attempt to use SetConsoleWindowInfo whenever possible so that
|
||||
the contents of the screen buffer are never wiped out. They also fix
|
||||
some previously misbehaving "scroll the screen" commands.

Bug Fixes
|
||||
---------
|
||||
|
||||

|
||||
i.e., never clear the screen buffer unless the user asked for it. Also
|
||||
fix screen escape sequences which attempted to scroll the screen.
