Now that we have `center-to-window-line', recenter needn't be in C
anymore -- its definition becomes a trivial combination of
center-to-window-line and redraw-frame.
C ChangeLog:
1998-04-30 Hrvoje Niksic <hniksic(a)srce.hr>
* dired.c (make_directory_hash_table): Constify.
* scrollbar.c (Fscrollbar_page_up): Use Fcenter_to_window_line
instead of Frecenter.
(Fscrollbar_page_down): Ditto.
(Fscrollbar_to_top): Ditto.
(Fscrollbar_to_bottom): Ditto.
* window.c (Frecenter): Removed.
Lisp ChangeLog:
1998-04-30 Hrvoje Niksic <hniksic(a)srce.hr>
* window-xemacs.el (recenter): Define.
