Shouldn't this ideally be const? Can be done when making AutoFile::read() const.

The basic idea is that serialization type should not be initialized when it is not needed. Same for the serialization version. So do this here for `AutoFile` and `HashVerifier`. `CAutoFile` and `CHashVerifier` remain in places where it is not yet possible.

Obviously not against getting this merged, but I think I'd have been more comfortable with another ACK? Perhaps someone can have a look here post-merge? Not a huge overhaul, but also not as trivial as a docs change. |
