\). The bsd version does print all the lines as expected, but the system V
\one does not. Also, the latest bsd version on our sun os does not either.

I say it should print every line indeed; apparently the System V version
of sed merely sets a flag "this line is to be printed later", which gets
cleared by the `d' operation. The following does work as expected:

	sed 's/.*/&/w foo
	d'
