This is the format I've gone for (more-or-less) in my RoleGraph view

emily from postgres (empty)
I think this is a good compromise.
Based upon prior comments going for something like the following is
undesirable: bob=asi/grantor
Agree. Membership options are not the ACL (although they have
similarities). Therefore, showing them as a ACL-like column will be
confusing.
So, please find attached the second version of the patch. It implements
suggested display format and small refactoring of existing code for \du
command.
As a non-native writer, I have doubts about the documentation part.
