Does this require an update to some bindings test expectations or a new bindings test?

http://clang.llvm.org/docs/AutomaticReferenceCounting.html#method-families says that we also need to check for alloc, copy, mutableCopy, and new. And maybe even init. I also was considering whether __attribute__((objc_method_family(none))) might not be better than NS_RETURNS_NOT_RETAINED, but I guess not.

Given that documentation, I’m thinking this regular expression should be:

    /_*(alloc|copy|mutableCopy|new)([^a-z].*)?/

That wouldn’t address the init family, but it would cover the copy cases, which I think could easily happen in practice.
