Subject: 25.1; Info-quoted face only works if curley quotes are displayed
Date: Tue, 25 Oct 2016 11:42:46 -0400

The Info-quoted face doesn't seem to do anything in Info
buffers.

It seems to be because Info-mode-font-lock-keywords assumes
curley quotes are used. From info.el: 

	(defvar Info-mode-font-lock-keywords
	  '(("‘\\([^’]*\\)’" (1 'Info-quoted))))

I'm using the macport and text-quoting-style is nil (and I
don't think I'm setting it specifically). Certainly I'm
displaying quotes as grave. 

FWIW I changed it to

    (setq Info-mode-font-lock-keywords
      '(("`\\([^']*\\)'" (1 'Info-quoted))))

and was able to get it working.

    `...' is the quoting used with Texinfo-4, whereas Texinfo uses the
    curly quotes.  The current code recognizes the curly quotes because that
    can be done much more reliably, whereas trying to highlight `...' is
    fraught with too many risks of either false positives or false
    negatives.
    
    While Texinfo 5's performance sucks rocks, the curly quotes output is
    The Right Way, in my opinion, so I don't think it's terribly important
    to highlight the old-style quotes: if you like this highlighting, then
    use Texinfo-5.
