"Change name "Gerd Moellmann" to "Gerd Möllmann" ?'

"Gerd M=C3=B6llmann" is already an AKA.
"=C3=83=C2=B6" is an encoding mangling of "=C3=B6":

--8<---------------cut here---------------start------------->8---
(decode-coding-string
 (encode-coding-string "Gerd M=C3=83=C2=B6llmann" 'latin-1)
 'UT-8)
=3D=3D> "Gerd M=C3=B6llmann"
--8<---------------cut here---------------end--------------->8---

So, I set `bbdb-add-aka' to 'sds-bbdb-add-aka':

--8<---------------cut here---------------start------------->8---
(defun sds-bbdb-add-aka (rec name)
  "Decide whether to add the NAME to REC's AKA.
See `bbdb-add-aka'."
  (cond ((member name (bbdb-record-aka rec)) nil)
        ((let* ((bytes (encode-coding-string name 'latin-1 t))
                (n1 (and (not (equal bytes name))
                         (decode-coding-string bytes 'utf-8 t))))
           (and n1 (not (equal n1 name))
                (member n1 (bbdb-record-aka rec))))
         nil)
        (t 'query)))
--8<---------------cut here---------------end--------------->8---

and I am not offered to add the mangled name to AKA.

However, I am still offered to _change_ the name to the mangled version,
because `bbdb-annotate-message' checks for AKA on line 439 like this:

--8<---------------cut here---------------start------------->8---
(member-ignore-case name (bbdb-record-aka record))
--8<---------------cut here---------------end--------------->8---

I am not sure how to handle this with the current setup - except by
adding the same code to both `bbdb-add-name' and `bbdb-add-aka'.

I think we need one function that checks if a name is already present
instead of two `bbdb-add-name' and `bbdb-add-aka'.

Thank you.
