[XeTeX] hyphenating words with hyphen

[Vadim Radionov]

Thank you, Jonathan,

That was my obvious typo -- i mixed up these two token lists.  This
way it works
fine!

Yours,

Vadim

PS.  Another problem I've tried to solve with  \XeTeXinterchartoks is
x-scaling the em-dash which is often two wide (and copyright sometimes
prohibits changing the font itself).   So I can put

\newXeTeXintercharclass\cyrdash
\XeTeXcharclass `\—\cyrdash
\XeTeXinterchartoks 0 \cyrdash = {\nobreak\hskip.125em\scalebox{.75}[1]}
\XeTeXinterchartoks \cyrdash 0 = {\hskip.125em}

leaving no spaces around the dash. But unfortunately this does not
work in the very beinning of the paragraph.
