That's not what John Keeping said[1]. I'm going to assume he was
wrong, but I don't think that's relevant for my point.

Either way, the meaning of builtin/ should probably be explained somewhere.

But init_copy_notes_for_rewrite() can *not* be used by anything other
than git builtins. Standalone binaries will never use such a function,
therefore it doesn't belong in libgit.a. Another example is
alias_lookup(). They belong in builtin/lib.a.
