Shouldn't be too hard.=20
(a) It should be optional, either as a flag to the existing ioctl, or
as a new ioctl.
(b) CONS_GETINFO will need to be extended (or we need a new ioctl for
the scrollback) to include information about how big the scrollback
buffer is.
(c) It might be worth providing a mechanism to let the application
specify a rectangular window that it wants to grab from the buffer.
I'm a bit busy most of this week, but I might be able to do this toward
the end of the week.
