This is due to a behavioral change of `append-to-buffer', which used
to preserve the point when the first argument coincides with the
current buffer. The following patch would work for this case.
Maybe other occurrences of `(append-to-buffer (current-buffer) ...)'
should also be checked if they work as intended.
