Import tex-nolbreaks-1.0 as print/tex-nolbreaks.

Use \nolbreaks{some text} to prevent line breaks in "some text". This
has the advantage over \mbox{} that glue (rubber space) remains
flexible. Most common cases are handled here (\linebreak is disabled,
for example) but spaces hidden in macros or { } can still create
break-points.
