 From stdin, to stdout, probably.

I don't think any of the tthree solutions given so far work. I was 
kind of bummed that my solution, short as it was, needed to access 
the file twice, once to count the lines, and once to list them. In 
particular, it really needed a file, and couldn't be used in the 
middle of a pipe. However, awk to the rescue. Fill in the dots, and

awk 'v10 {print v10} {v10=v9} {v9=v8} ..... {v2=v1} {v1=$0}'

can actually be used between stdin and stdout.

I <heart> awk.
