I can do that.

How do you feel about having the duplicate check for the short_ref? We
*already* check this inside init_notes_check() which is called right
after this.

I think that we should keep it but can't find a consistent way to
avoid the duplication.

In addition, we already provide the tests for merging into and from
non-notes refs.
