Ok. Some things are available in different ways perhaps because of
historical reasons and backward compatibility.

Didn't you say already that "we can have 'signature' as an atom too",
so isn't it already defined as an atom? Does `%(contents:signature)`
work for commits while '%(signature)' doesn't? And what happens when
it doesn't work?

Ok, I guess all the above arguments would be new.

It would be nice to see, at least for the atoms or arguments that you
are planning to, or have already, worked on, a list showing how each
formatting option in pretty.c maps to one or more atoms possibly with

For example something like:

%GS: show the name of the signer for a signed commit
  maps to: %(signature:signer)
  status: yet to be implemented
