Comments shown by default in 1.0?

Hi,
In .72, in order for b2comments.php to make itself visible (if you have it included), you have to have “&c=1” somewhere in the query string. In 1.0, the included wp-comments.php shows up whether the query string calls it or not. (And even if I include “&c=0” in the query string, in fact.)
What I would like here is to be able to click to a single-post page without comments showing up by default, like in .72. I can’t find anything different in the 1.0 documentation thatn in .72, so I’m assuming that the way I want it isn’t too unreasonable.
Any thoughts?
