So `' quoting style is common for info files. I checked it was used for
function selection in libc and readline info files. Also it was used in GNU
Make, R, Autotool and other manuals.

So having highlighting for `' in info mode is good thing for Emacs user
(compare with emacs-lisp-mode, where it was highlighted).

This is my vote up.
