Storing notes refs outside of refs/

  Every push to our server creates a note at .git/refs/notes/p4notes 
with the equivalent Perforce changelist number, so Git-controlled code 
and Perforce-controlled content can stay in sync.

gitk --all and Git Extensions (out of box) show all entries in the 
.git/refs/.  The p4notes entries are intermixed with the regular branch 
content.  This creates a HORRID visual mess.

I tried manually moving .git/refs/notes/p4notes to .git/p4/p4notes.

"git log --show-notes=p4/p4notes" fails, but assigning 
core.notesDisplayRef=p4/p4notes succeeds.

The best part is, the refs/* namespace is no longer cluttered with junk!

However, "git push origin p4/p4notes:p4/p4notes" fails with the error: 
Unable to push to unqualified destination: p4/p4notes.  The destination 
refspec neither matches an existing ref on the remote nor begins with 
refs/, and we are unable to guess a prefix based on the source ref.

Is there a way to make the "git push" work?

Thanks!
