DEFUN ("set-window-point", Fset_window_point, Sset_window_point, 2, 2, 0,
"Make point value in WINDOW be at position POS in WINDOW's buffer.")
(window, pos)
Lisp_Object window, pos;
{
register struct window *w = decode_window (window);
CHECK_NUMBER_COERCE_MARKER (pos, 1);
if (w == XWINDOW (selected_window))
Fgoto_char (pos);
else
Fset_marker (w->pointm, pos, w->buffer);
return pos;
}
The function's use of Fgoto_char(pos) changes the value of point in the
wrong buffer if the current buffer is not the same buffer as that of the
selected window, i.e.
(not (eq (window-buffer (selected-window)) (current-buffer)))
