I decided to bisect the issue.  Between each good or bad, I did
 (cd ~/git/gnus; make clean; make; cd lisp; make tags)
and started a fresh emacs on the results.

It turns out that the issue has been there for a while (and also that
the bisect result isn't very useful... see below...:-) ).

The reason I haven't noticed it, is that I get it on some articles.  And
one of the offending articles have:
 Content-transfer-encoding: 8BIT
 Content-type: text/plain; charset=UTF-8

Could it be CTE 8BIT that is the culprit?  There was something about
that in the most recent thread (the 2008 thread from this group).

Articles that display correctly, are
 Content-Type: text/plain; charset=ISO-8859-1
 Content-Transfer-Encoding: quoted-printable

and (curiously):
 Content-transfer-encoding: 8BIT
 Content-type: text/html; charset=utf-8

(I'm not sure what I use to render HTML.  But should it matter, if the
problem is getting 8BIT stuff from nnimap?)


Anyway... the "offending" commit is this one:

sb@aa1steinar:~/git/gnus$ git bisect good
df6ac45b952171e7e709c1b0bf23cc7346429f81 is the first bad commit

    Reimplement nnimap, and do tweaks to the rest of the code to support that.
    
    * gnus-int.el (gnus-finish-retrieve-group-infos)
    (gnus-retrieve-group-data-early): New functions.
    
    * gnus-range.el (gnus-range-nconcat): New function.
    
    * gnus-start.el (gnus-get-unread-articles): Support early retrieval of
    data.
    (gnus-read-active-for-groups): Support finishing the early retrieval of
    data.
    
    * gnus-sum.el (gnus-summary-move-article): Pass the move-to group name
    if the move is internal, so that nnimap can do fast internal moves.
    
    * gnus.el (gnus-article-special-mark-lists): Add uid/active tuples, for
    nnimap usage.
    
    * nnimap.el: Rewritten.
    
    * nnmail.el (nnmail-inhibit-default-split-group): New internal variable
    to allow the mail splitting to not return a default group.  This is
    useful for nnimap, which will leave unmatched mail in the inbox.
    
    * utf7.el (utf7-encode): Autoload.
