Details:

I would like to see a command (which I could bind to a key) to redraw the
screen and the scrollback buffer.  In other words, it would push the lines in
the scrollback buffer back to the screen then redraw the current screen (like
^a ^l).  

It is possible to scroll back up using the editing mode but it is MUCH more
convenient to be able to use the scrollbar in a program such as Putty.

When the scrollback buffer is redrawn, it should preserve the color of the
text.

Similarly and perhaps this should be a separate feature request, there could
be an option to always redraw the scrollback buffer each time the user
switched to a screen.  This will cause obvious flashing on large scrollback
buffers.  I wonder if it is possible to get around that by either redrawing
off the screen or by using the terminal's own alternate screen while redraw is
taking place.
