[ale] awk fun

[Jim Kinney]

bozo me. The self-reply was after I had merged the broken one-liner with the
next broken one-liner and fixed both.

Yes, the $i was a fubar. But my run gave really strange results:
5778
0
4753
105
378
0
3486
0
5460
0
5253
0
3570
105
0
1
which looks like FS = NULL

print NF is correct as it does the "RightThing". William was right.
