bug#12951: 24.3.50; adviced functions have no docstring

[Roland Winkler]

cat > ~/foo.el <<EOF
(defadvice beginning-of-buffer (before deactivate-mark activate)
  "Add friendly greeting."
  (message "Hello world.  This function is advised")
  (sit-for 1))
EOF

emacs -Q -l ~/foo.el
C-h f beginning-of-buffer

Emacs says that this function is advised and it displays the
docstring of the advice. But the original docstring of
beginning-of-buffer is not displayed.

No such problem with emacs 23.1 which displays both the original
docstring and the docstring of the advice.
