The `heads()` revset function with one argument is the counterpart to `roots()`. Without arguments, it returns the visible heads in the repo, i.e. `heads(all())`. The two use cases are quite different, and I think it would be good to clarify that the no-arg form returns the visible heads, so let's split that out to a new `visible_heads()` function.
