So I go from newline after X columns and a blank line between paragraphs to long lines with a single newline between paragraphs. The simplest algorithm would be to remove all newlines except double newlines (and convert those to single). If -s was specified, we would only remove newlines after spaces and tabs (or unless there was no space in that line). Finally, if -w was specified, we would re-wrap at that width.

  You mean character 182 I take it, it's in the extended ascii set.
May I remind you that ascii was designed for teletypes not video
and they had a very limited and mechanical action set by default,
although some did have the extra "character" punches available as an
optional set when ordering. I know mine did and it cost the earth to
have them as I had to justify the added expense before work allowed it
to be ordered.
