Right I forgot to mention that I had to
  tr -d '\r'
first. Thanks for mentioning that.

Close, but no cigar. That sed command introduces extra blank lines. It is incorrect. ssam reigns supreme!

  tr -d '\r' < 2488-0.txt | ssam -e 'x/\n+/ v/\n\n+/ c/ /' | wc -l
7667
  tr -d '\r' < 2488-0.txt | sed '/^$/!{H;d;};p;x;s/\n/ /g;' | wc -l
7782
