Re: decode-char & utf-8-fragment-on-decoding

[Dave Love]

I'm sorry, I think I finally got it after confusion between two
different issues and paying insufficient attention.  Thanks for
persisting.

It's indeed a bug that

(eq utf-8-translation-table-for-decode
    (get 'utf-8-translation-table-for-decode 'translation-table))
  => nil

I think it's more consistent to fix the custom stuff to keep the
things in sync rather than just fixing decode-char, and there may be
similar problems elsewhere.  I'll look at fixing it.
