Recent makeinfo on @item generates forward quote 'foo' rather than
backquote `foo' which it used to.  info-look.el doesn't match the
forward 'foo' in various places which are @table (as opposed to @defun
etc).  For example with the glibc manual,

    M-x c-mode
    DBL_MAX          # type this
    C-h S            # and look it up
    =>
    goes to "Floating Point Parameters" node,
    but does not go down to the DBL_MAX entry

I suggest adding ' to the prefix regexps of relevant doc specs.

The latex-mode bit is a further small change to its suffix to match
\frac and \sqrt of the latex2e.info.

	* info-look.el (c-mode, bison-mode, makefile-mode)
	(makefile-automake-mode, texinfo-mode, autoconf-mode, awk-mode)
	(latex-mode, emacs-lisp-mode, sh-mode, cfengine-mode): Match both
	`foo' and 'foo' for @item and similar.
	(emacs-lisp-mode): U+2018,U+2019 in emacs.info and elisp.info too.
	(latex-mode): Match multi-arg \frac{num}{den} or \sqrt[root]{n} in
	suffix regexp
