unexpected result of tex.sprint() in verbatim env.

[dohyunkim]

I get a bunch of unexpected \FontspecSetCheckBoolTrues in the pdf with the MWE compiled with lualatex:

\documentclass{article}
\usepackage{polyglossia}
\setmainfont{DejaVuSerif.ttf}
\setmonofont{DejaVuSansMono.ttf}
\setdefaultlanguage{greek}
\begin{document}
α \verb|α|
\end{document}

because tex.sprint() in fontspec.lua currently does not have optional parameter denoting a catcode table. Everything is ok with the code around line 30 in fontspec.lua being changed into the following:

local latex = luatexbase.registernumber("catcodetable@latex")
local function tempswatrue()  tex.sprint(latex,[[\FontspecSetCheckBoolTrue ]]) end
local function tempswafalse() tex.sprint(latex,[[\FontspecSetCheckBoolFalse]]) end

Oops, apologies! If you could put together a pull request I'm happy to accept it directly. Many thanks

Seems like this issue also causes ! LaTeX Error: Something's wrong--perhaps a missing \item. error when using Verbatim environment from fancyvrb package (similarly while non-english languages set in preamble). Reverting to 2.4e version of fontspec helps.
