That (specifically 'merge') is not my real worry.  It's the other
way around, actually.

Because expand_notes_ref() makes sure that any given notes ref is
prefixed appropriately to start with refs/notes/,

    git notes --ref=refs/heads/master add ...blah...
    git notes --ref=refs/tag/v1.0 add ...blah...

would be a sensible way when somebody wants to keep a forest of
notes refs, one per real ref.  Wouldn't they have already been
trained to spell "refs/heads/master" when they want to refer to
refs/notes/refs/heads/master because of this?
