Dan claims that after enough replies from different people, the
recipeint lists get so long that mail sofware breaks.
I pointed out that this, among other problems, happens _by default_.
While this is
true in principle, I've never seen it happen in practice.
And you'd understand the reason if you had read my next paragraph: ``Of
course, people don't let the header grow so much. They trim it down to
just the list address. But this introduces some of the same problems as
reply-to munging; for example, it destroys cross-posted discussions.''
