Well, the tmtowtdi dogma has its drawbacks. Here's another sed-script
that does the exact same thing:

	sed '1!G;h;$!d'

That being said, perl borrows most of its regex notation from sed, so
it's not as if perl is easier. This is just the top-end of the scale
that things like "sed s/foo/bar/" is at the bottom of ;-)
