The git note loading logic isn't namespace aware,
so rather than reimplementing it all
this just adds the default note file in the current namespace.

I'm not sure.

I thought it was just that its intended user was glob expressions
provided by the command line or config,
and that it was just a leaky abstraction,
but it looks like there might be validation code preventing refs from
including glob characters.

I'll take a look at the git code to see if I can prove this hypothesis.

Not that I could find, but if my hypothesis proves correct it can go
away entirely.
