[***SPAM***] \setscript blocking \hskip functionality

[hwitloc]

I found that using \setscript{nihongo} breaks the functioning of \hskip.
Here is a minimal example.  MKIV required.  Text source is UTF-8 encoded text.

In the first case without \setscript the Japanese \hskip properly functions, but just after the \setscript macro it fails (without err or mention).  However, it is interesting to note that \hfill does work in both cases with standard alphabet text.


%--------------------------------
\usemodule[simplefonts]
\setmainfont[ipaexm]	% using a font having Japanese characters 

\starttext
\underbars{Without setscript:}

Alphabet\hskip 2cm text
 
    漢字\hskip 2cm 文書

\setscript[nihongo] 
\underbars{With setscript:}

Alphabet\hskip 2cm text 

    漢字\hskip 2cm 文書

\stoptext
%-------------------------------- end

It's because spaces are stripped and there is currently no distinction 
in luatex (on the todo list is to tag glue coming from spaces with their 
own subtype). I made a cheat. For the moment only in the japanese 
analyzer but it might also be needed for korean and chinese, so can you 
check that with cjk context users?

\usemodule[art-01]

\enabletrackers[scripts.*]

\definefont[testfont][ipaexm.ttf][script=kana,language=jan]

\startTEXpage
     \startformula test \stopformula \par
     \testfont \startscript[nihongo]\ruledhbox{漢字\hskip 2cm 文 
書}\stopscript\par
     \testfont \startscript[nihongo]\ruledhbox to 7cm{漢字\hfill 文 
書}\stopscript\par
     \testfont \startscript[nihongo]\ruledhbox{漢字文書}\stopscript\par
     \testfont \startscript[nihongo]\ruledhbox{漢字 文書}\stopscript\par
     \testfont \startscript[nihongo]\ruledhbox{漢字\kern 2cm 文 
書}\stopscript\par
     \testfont \startscript[nihongo]\ruledhbox{\hskip 2cm 漢字文 
書}\stopscript\par
\stopTEXpage

\stoptext

I'll upload a new beta.

Btw, what gives these threads a spam subject.
