Just reading this, I was confused about what the patch actually did.
Reading the code, I figured it out, but perhaps an example would make
sense. Like:

  This means that we will print:

    p 1234abcd subject line

  in the todo file rather than:

    pick 1234abcd subject line

And then of course that left me wondering why somebody would want to do
that. I understand wanting to _type_ the abbreviated version, but surely
it's not too much work to read the full word?

Then I saw:

That makes some sense. it should probably be part of the commit message,
so that future readers of "git log" understand why the change was made.

Similar to the commit message, this might need to go into more detail.
It was not immediately obvious to me that "command name" means the
command-names in the instruction list.
