I think I've finally fixed this problem.

In 21.3, redisplay would adjust window vscroll to make the bottom line
visible, but in CVS emacs, we no longer do that.  Instead, the recenter
code now performs some extra calculations to make the current line end
up as the last (fully visible) window line.

As a result, there next line in the buffer may be partially visible
at the bottom of the window, but I cannot do anything about that.
