Thanks.

It's okay, but for a single minor nit:

> +macro list

I think we should delete the first sentence.  Users who read NEWS do
not know that these commands were documented, but not implemented.
Just saying "These commands allow macros to be defined, undefined, and
listed interactively from within GDB." is enough

Thanks.
