@c Some plain TeX macrology to wrap text in \hbox{} only if the text
@c contains no hyphens.
@iftex
@tex
\newif\ifdash
\long\def\dashp#1{\expandafter\setnext#1-\dashphelper}
\long\def\setnext#1-{\futurelet\next\dashphelper}
\long\def\dashphelper#1\dashphelper{
\ifx\dashphelper\next\dashfalse\else\dashtrue\fi
}
\def\lw#1{\leavevmode\dashp{#1}\ifdash#1\else\hbox{#1}\fi}
@end tex
@end iftex
@c A Texinfo binding for the plain TeX above. Analogous to Texinfo's
@c @w, but for Lisp symbols. AFAICT, the comment characters are
@c necessary to prevent treating the newline as a space.
@macro lw{word}
@iftex
@tex
\\lw{\word\}%
@end tex
@end iftex
@ifnottex
\word\@c
@end ifnottex
@end macro
