This, instead, works also with registers:
-------------------------------------------------
--
\unexpanded\def\wordorparagraphright{\dosingleempty\WordOrParagraphRigh
t}
\def\WordOrParagraphRight[#1]{\groupedcommand{\setbox0\hbox\bgroup}
{\egroup\newdimen\myBoxWd\myBoxWd=\wd0
\ifdim\myBoxWd < .7\hsize
\wordright{\box0}%
\else
\startalignment[flushright]\leftskip=.3\hsize plus 1fil\unhbox0
\stopalignment
\fi}}
\starttext
\input sapolsky \wordorparagraphright{\it other text} \par
\blank
\input sapolsky \wordorparagraphright{\it other text, this time longer}
\par
\blank
\input sapolsky \wordorparagraphright{\it other text, this time
much much much much much much much much much much much much
much much much much much much much much much much longer} \par
\stoptext
---------------------------------------------------
A doubt: i'm using box0, is it dangerous?
I tried with scratchbox, but it doesn't work, then i moved to box0, and
it seems to work, even with a big file (with a big register too) of
mine.
