I thought that recenter-redisplay set to t, which causes a complete redraw of the frame, should also redraw the *Messages* buffer. > And window-scroll-functions aren't called when the window is > not scrolled. 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.
