Ancient sort version?

[Kevin O'Gorman]

I'm looking at an old sourceforge project
   http://sourceforge.net/projects/sicsh
as I try to learn the autotools.

This project took a little tweaking just to make, and even then it
stumbled a bit.  I saw an error message that led me to this line in a
script
>  if grep -v "^: " < "$nlist" | sort +2 | uniq > "$nlist"S; then
where the sort step was complaining about the "+2" command-line option.

Does anybody recollect sort(1) ever taking such an option, and if so
what it meant?
