Gaaah.

The first line in the original is removed while the perl version
seems to just makes it empty -- ah, you remove the trailing LF
as well there.  I've never seen this done like this, but OK.

It would have been more obvious if it were written like this:

	$_ = "" if ($. == 1);

but probably it is just me.

Thanks for the patch.
