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. >> Second, do you even read what you reply to?

There just isn't enough room to store the information. 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. >> But speaking of length limits, the lines in your postings are too long, >> according to Usenet convention.

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. > Might be a good reason to use a URL shortener. URIs can posted to a newsgroup/mailing list without shortening them, by wrapping them without breaking them.
