This is awfully confusing. Sometimes your are answering Richard,
sometimes me. Try to avoid doing this in the future. I don't know
if you have actually confused us two, or if you are merely trying
to multitask by answering us simultaneously. :-(

In the days before ultra-cheap storage, the Usenet standard was
to trim the quotations to just what was necessary for readers to
identify the context of one's response. Violators of this standard
were constantly castigated. I don't attempt to follow the old
standard, but I do trim portions of conversation that are not
relevant to me. Now I see complaints of trimming, while the posts
become ever more bloated with dead branches of conversation. This
strikes me as absurd.
