Please do not insult my intelligence. I have a problem with that you are
not marking the omission of considerable parts of *my* text, here giving the
wrong impression that I did not start my follow-up in an encouraging way.

You are the one introducing “arbitrary” here. I am not at all convinced,
but this discussion is beyond the scope of this newsgroup/mailing list.

No, quotations ought to be word-wrapped, preserving paragraphs, in order not
to exceed that limit. That is why the recommended line length limit for
posting is not 80 characters, but something from 68 to 78.

URIs can posted to a newsgroup/mailing list without shortening them, by
wrapping them without breaking them. Will you *please* read [2] to clarify
that misconception of yours?
