Great! Simple and effective. And more surgical than pandoc's global
solution. But now a question arises... Your code clearly solves the
problem that led to the declaration of org-latex-line-break-safe,
without foreseeing any unwanted effects, since it is the solution that
is usually recommended from LaTeX. So, if this code is included in Org,
what is the future of org-latex-line-break-safe?
