bug#25483: 26.0.50; Not possible to put ASCII quote in result of format-message

[Philipp Stephani]

Evaluate:

(format-message "'")
"’"
(format-message "\\='")
"\\=’"

Note that it is apparently impossible to put an ASCII quote into the
result of format-message.  Quoting with \= doesn't appear to work.

As its doc string says, text-quoting-style determines this:

(let ((text-quoting-style 'straight))
  (format-message "'"))
"'"

You can do (format-message "%s" "'").

As somebody else has noted, you need to set or bind text-quoting-style
to the symbol `grave'.

Note that as from 2016-05-10, text-quoting-style no longer translates
curly quotes, so `grave' essentially means "no change to any quoting
character" - which is presumably what you really want.  :-)
