There is a bit of redundancy here. I wonder if it could be described
more succinctly. For instance, instead of all the above, perhaps:
Group commits by `<type>`, which can be one of:
- `author` (default)

Is this leaking strbuf 'ident'?
(Ditto for the "author" case as mentioned already in the patch 6/14 review.)
