That's exactly what I thought, and that's why I posted a patch that
changes (append-to-buffer (current-buffer) ...) to (prepend-to-buffer
(current-buffer) ...), rather than reverting append-to-buffer.

If it is changed in the trunk, then it might be good to add some
notices to documents in Emacs 23.2, telling the behavior of
append-to-buffer might change in future with respect to the current
buffer, and suggesting prepend-to-buffer for those cases to make the
behavior consistent.
