This explanation should probably go in the commit message.

I am not sure the behavior afterwards is right, though. With git-log, I
see the following behaviors:

  1. With --notes, notes are displayed.

  3. With --no-notes, notes are not displayed.

  3. With no options, notes are displayed (i.e., we default to --notes).

  4. With --format=%N, notes are displayed (automatically, without
     having to use "--notes").

Shouldn't rev-list behave exactly the same way, except for (3)? That is,
it should respect the options in the same way, but default to not
showing notes?

Even with your patch, we seem to be violating points (1) and (4).
"--notes" does nothing by itself, and you need to use it to make "%N"
work.

For (4), you need to use userformat_find_requirement, as git-log does.
I'm not sure without digging how to make (1) work.
