_almost_ all socket options inherit across accept()?

Now that Matt Thomas helped me understand where the listen socket's options
are copied to the accept socket, I think the following patch is required for
the low-water marks to inherit across accept() like the other socket options.
All else seems to be copied correctly already.
Opinions?

I think that the change is correct.
