Pure sophistry.

I don't know what shadow glyphs are, and don't particularly care - they're
irrelevant.  As I've said more times than I can count, the problem is
that curly quotes are used in help buffers, messages, etc., not the way
they get displayed.  I solved that problem by introducing
`text-quoting-style', and you have reintroduced the problem by removing
`text-quoting-style'.

Please come up with an actual solution, not an irrelevance.  Or else put
`text-quoting-style' back again.

For what value of "work"?  Will it enable the quoting behaviour to be
configured to be the same as in Emacs-24.5?  It not, it's no good.

`text-quoting-style' is necessary.  Please put it back, or replace it
with something which works properly.
