After reading "Angle brackets are automatically given", seeing that
the argument description has manually spelled "<arg>" gave me "Huh?".

Without " named <arg>" there is no such confusion.

Of course.  That is why I suggested to do without " named <arg>"
part---I didn't mean to suggest not to add the example.  I also
think that you can demonstrate something other than '=' (whose usage
is already shown with "bar=" above) here as well, but I think we can
go either way.

You already are by saying the "Angle brackets are automatic", aren't

OK, that is fine, then (I'd prefer a field name not to sound like
arrrgh, but that is an entirely different topic).

Sounds good.
