I built emacs from git (commit a486fabb41cdbaa5813c2687fd4008945297d71d) via

  git clean -dxf
  ./autogen.sh
  ./configure
  make all install

I then invoked it like this

  open --new
~/git-repositories/3rd-party/emacs-master/nextstep/Emacs-master.app/ --args
-Q

I then invoked info on the file elisp.info, something like this (I'm not
sure exactly what I typed, but it wound up leaving this in command-history)

  (info "~/git-repositories/3rd-party/emacs-master/info/elisp.info" nil)

I then typed g Keys SPC in SPC Documentation RET

I then noticed that the description of text-quoting-style looked like
this:

     -- Variable: text-quoting-style
         The value of this variable is a symbol that specifies the style
         Emacs should use for single quotes in the wording of help and
         messages.  If the variable's value is `curve', the style is
         \342\200\230like this\342\200\231 with curved single quotes.  If
the value is
         `straight', the style is 'like this' with straight apostrophes.

It's supposed to have actual curly quotes instead of octal escape sequences.
