Of course "cat -n" is almost as evil as "cat -v" (-v has a
sublanguage) and doesn't work on Plan 9:

	cpu% cat -n
	cat: can't open -n: '-n' directory entry not found

One could use "pr -tn" instead of the little awk script, but the
difference in speed really isn't that great.  Reading a cached ~2.5MB
file of ~250K lines,

cpu% time awk '{print NR, $0}' test >/dev/null
2.85u 0.13s 3.53r 	 awk {print NR, $0} test
cpu% time pr -tn test >/dev/null
1.75u 0.13s 2.18r 	 pr -tn test
