My "git log" shows notes from ref/notes/commits by default without alias
or config, and that is what I want to override per command (to show
Thomas' notes, e.g.).

I somehow stopped proposing behavior changes. Guess why? (I know I have
my occasional relapse, but still...)

Also, "git notes" has "--ref". Maybe this (which may be what you
proposed above):

--notes: show standard notes
--notes=<ref>: show notes from <ref> only
--notes --notes=<ref>: show standard notes + those from <ref>
(i.e., if any notes argument was given they accumulate; a single
argument does not add to, but replaces the default)
--no-notes: you guess it

One could deprecate --[no-]stand-notes as well, then.

Changing status "PATCH" back to "PATCH/RFC"...
