Maybe something like deadbeef@{notes[:namespace]}? The ability to
embed the notes namespace to use in the call is very useful to be able
to access all the notes with a single git call.

I agree with you on this, btw. As I mentioned in the other message,
these would just be workarounds for the current lack of support of
these features in core. I'd probably try and have a go at the thing
myself, too (i.e. first implement the core functionality, and then use
it in gitweb), but I honestly don't feel confident enough to hack at
git core.
