Nicer, much nicer.

Note that there is a leftover caller that uses the symbol without noticing
that it has been retired. I'll fix it up locally when I queue the series
to 'pu'.

Parsing is good, and not reading trees is very good.
It is silly to put yourself down after doing both of these very well by
saying "even if we don't care about it"---you obviously do care about
making it earier for other people to build on top of your code. Otherwise
you would have left the code unchanged from the previous round ;-).

Unlike default_notes_tree, the above two can become static, as you made
the new logic better contained to this file and accessible only via
accessor functions.

I'll s/_ref()/_ref(void)/ here.

As you are retiring format_note() as a public interface, and instead
making format_display_notes() as the primary API for the callers, the
former should be made static to notes.c along with the large comment
describing how to call it. It may also be worth telling people how to
call this new public interface with similar comment here.

I'll s/_WITH_REF// here.

Nice; multiple --show-notes=... will accumulate in the order given. I
knew you won't be stupid to make this a colon separated string, but I had
to double check ;-).
