Hello, Helmut.

In article <address@hidden> you wrote:

Yes.  It's a misfeature indeed.  It's already caused a lot of bad
feeling amongst Emacs developers.  The person behind the change, Paul
Eggert, simply pushed it through without first securing agreement from
Emacs as a whole, and had the political skills to prevent a consensus on
the matter prevailing.  I think he regards it as "modern and desirable"
to display what he thinks the programmer wanted, rather than what the
programmer actually wrote.

As for actually polling users, such as yourself, first?  Hmmm.

Yes.  But no, such a strategem would be "incompatible" with the way
things were when rushed through for Emacs 25.  I did my best to make the
nil value of text-quoting-style mean "do nothing", but was overruled,
again on grounds of "compatibility".

So, you're not the first to suffer from this misfeature, and you'll
certainly not be the last.  I think it vanishingly unlikely that it will
be fixed.

Sorry.
