 This function acts like @code{format}, except it also converts any

+A format that quotes with grave accents and apostrophes @t{`like
+this'} typically generates curved quotes @t{‘like this’}.  In
+contrast, a format that quotes with only apostrophes @t{'like this'}
+typically generates two closing curved quotes @t{’like this’}, an
+unusual style in English.  @xref{Keys in Documentation}, for how the
+@code{text-quoting-style} variable affects generated quotes.
