Sorry, I don't understand your question.  The output is
correct in all prior Emacs releases, as far back as Emacs
22 (not 20).

But it is incorrect in Emacs 26.0.90 and later, as I said.
(And it is incorrect in Emacs 20, in the way I showed.)

What part of this is not yet clear to you?  The output
is correct, with a normal hyphen, with Emacs 22 through
25.3.1.  The output is incorrect for Emacs 26 and 27.
(And the output is incorrect for Emacs 20.)

I don't understand what you are saying.  As I said, the
output looks correct since Emacs 22, until Emacs 26.
It has not been "incorrect since long ago".  It is
incorrect since Emacs 26 (pretest).
