Aside: I'm not sure this is the most convenient rule to use after all.

Example:

 $ git log --notes-ref=charon/notes/full
 fatal: unrecognized argument: --notes-ref=charon/notes/full
 $ git log --show-notes=charon/notes/full
 warning: notes ref refs/notes/charon/notes/full is invalid
...
 $ git log --show-notes=remotes/charon/notes/full
 warning: notes ref refs/notes/remotes/charon/notes/full is invalid
...
 $ git log --show-notes=refs/remotes/charon/notes/full -1

And now that I think of it, the revision args parser uses its own code
for this...

Regardless, this patch is a step in the right direction imho.
