Hi Ilya,

thanks for looking into this and the patch.  For the first part, I have
tendencies to keep the current state as " will give you different
results depending on font encoding, example:

--8<---------------cut here---------------start------------->8---
\documentclass{article}

\usepackage[OT1,T1]{fontenc}
\usepackage[utf8]{inputenc}

\setlength{\parindent}{0pt}

\begin{document}

The highlighting of ``this" is wrong \\
The highlighting of ``this'' is wrong

and

\fontencoding{OT1}\selectfont
The highlighting of ``this" is wrong \\
The highlighting of ``this'' is wrong

\end{document}
--8<---------------cut here---------------end--------------->8---

Run this file with pdflatex: With T1 encoding, " in .tex file gives " in
your output file.  '' results in ”.  So to be on the safe side, I think
'' is the way to go for Right Double Quotation Mark.

I don't use this feature so I can't tell.  Others?
