a) The highlighting of ``this" is wrong (does not stop at the
   finishing quote).
b) Handling of super/subscripts is not compatible with 'composition;
   e.g., with
         latex-pretty-symbols.el
   or https://stackoverflow.com/questions/22937393/emacs-lisp-prettify-symbols-mode-for-latex?rq=1

The patch is appended.

Enjoy,
Ilya
