I see you reverted translation by ‘format’ of curved quotes in format strings. 
While this preserves compatibility better, it also causes some diagnostics to 
use curved quotes even if ‘text-quoting-style’ specifies an ASCII style, which 
likely would cause problems in traditional Emacs setups that prefer ASCII styles.

One possible fix is along the lines of one of Dmitry's earlier suggestions: add 
a function that translates a curved-style string to the style specified by 
‘text-quoting-style’, and have ‘message’, ‘error’, etc. invoke the new function 
on the format string before passing it to ‘format’.  This avoids affecting the 
behavior of ‘format’ itself and so should address the compatibility concerns 
that you and Dmitry noted.  I installed commit 
fbb5531fa11d13854b274d28ccd329c9b6652cfc in an attempt to do that.  Comments as 
usual are welcome.
