There was inadequate example in the mail which I posted yesterday, sorry.

I re-explain the second problem again.

I found that the problem exists not in the revert-function but in the
goto-char function.

First, set Emacs to display two windows, say 'top' and 'bottom'.  'top' and
'bottom' window must be different each other.  'bottom' window must have some
characters in it.

Define the following program.  Of course, replace "bottom" within get-buffer
function with the actual buffer name.

    (defun test ()
      (set-buffer (get-buffer "bottom"))
      (goto-char (point-max)))

Move the cursor to the beginning of the 'bottom' window, then move it to the
'top' window.

In the 'top' window,  execute (test).  

After execution, move the cursor to the 'bottom' window to examine its
position.

The cursor should have moved to the end of the buffer (I think so), but it
still stays at the beginning.

Is it Emacs feature?

Is there anyway to control the cursor position of the buffer while another
buffer being 'current buffer'.

Thanks.
