Always treat children of examples as examples

There was supposedly logic in both HTML and docbook to treat children
after the first one as something different, but it couldn't possibly
be triggered (nothing ever advanced the counter)! So just take that
out. I couldn't come up with an example that could produce multiple
children anyway.
