I thought that recenter-redisplay set to t, which causes a complete
redraw of the frame, should also redraw the *Messages* buffer.

I see that the window is scrolled while typing C-l C-l C-l ...
(recenter-top-bottom). I tried in the middle of a large buffer
like 'C-h C-t' (view-emacs-todo).
The first C-l puts the current line in the middle, refreshes
the *Message* buffer, and displays the message in the echo area.
The second C-l puts the current line at the top, DOESN'T refresh
the *Message* buffer, but displays the message in the echo area.
The third C-l puts the current line at the bottom, DOESN'T refresh
the *Message* buffer, and DOESN'T display the message in the echo area,
which means window-scroll-functions is not called at all in this case.
All three have a different effect.
