Should DDoc list all publics by default?

[Chris Miller]

I would very much want this. This way you can also see what you forgot to  
make non-public; you don't want people to depend on stuff you intended on  
being internal (which seems to happen quite often from Phobos).

Also, I'd like a way to specify "don't include in documentation" from the  
source. deprecated could be one way, and/or something like /// ddoc-exclude
