I disagree. Just imagine that you have a title with more than nine
words: To be able to display it correctly on old non-groff systems you
*must* use double quotes. For this reason I recommend to always use
double quotes, which will never cause a problem.
In other words, I prefer to have users apply a recipe that will always
work. Telling them `Always quote a multi-word title' is IMHO easier
to remember than saying `Use quotes if you have more than nine words
in a title'.
Perhaps a future release of groff can completely drop compatibility to
old non-groff systems, but I guess this won't happen in the
forthcoming version.
