man 1 cat:

-n      Number the output lines, starting at 1.
-b      Implies the -n option but doesn't number blank lines.
-s      Squeeze multiple adjacent empty lines, causing the output to be        single spaced.


cat -s -n doesn't number all output lines, it behaves like cat -s -b.

Testet on NetBSD 2.0 & 3.0
