[luatex] font feature with new luaotfload

[Hironori KITAGAWA]

Hello,

I tried the following source with TeX Live 2013 pretest.

---
\documentclass{article}
\usepackage{fontspec}
\begin{document}
\fontspec[RawFeature=+pwid]{KozMinPr6N-Regular}
A…B

\fontspec[RawFeature=+fwid]{KozMinPr6N-Regular}
A…B

\end{document}
---

But I got unintentional result from LuaLaTeX with luaotfload v2.2.
In concrete terms, '…' in the second line should be replaced by 
its fullwidth variants CID #668 (as in koz-xetex.pdf), 
but it doesn't so ('…' is not replaced) in koz-luatex.pdf. 


The following patch solve the problem for the time being
(maybe this isn't a good solution):
