I notice that `recenter' has the effect of calling (redisplay t); that
is, it seems to force a redisplay. I don't see this mentioned
anywhere. It might be helpful to mention it. We might want to mention
it in the Elisp manual node Textual Scrolling, where `recenter' is
covered, and also in node Forcing Redisplay, where redisplay is
covered (with an xref to Textual Scrolling).
Users who want to both recenter and redisplay might want to know
that `recenter' alone suffices.
Users who do not want to force a redisplay might want to know that
`recenter' does that.

In the docstring:
If arg is omitted or nil, erase the entire frame and then redraw with
point in the center of the current window.
In the Emacs manual:
It also clears the screen and redisplays all windows; this is useful
in case the screen becomes garbled for any reason (*note Screen
Garbled::).
In the Elisp manual:
If @var{count} is @code{nil}, @code{recenter} puts the line containing
point in the middle of the window, then clears and redisplays the
entire selected frame.
However, the docstring for recenter-top-bottom (new to Emacs 23) did not
mention this; I've updated it accordingly.
