Core Marker toString redux

[Gary Gregory <ga...@gmail.com>]

I think I've broached this topic a while ago but I still do not have a
solution.

When I use a Core marker in a pattern layout, the toString() I get is
pretty ugly, _especially_ if the marker has a parent. Nested [ ]'s, very
hard to read, looks nasty in a text log.

My markers do not have multiple inheritance so I would be happy with
a Parent0.Parent1.Leaf toString.

(1) Should the toString be smart and detect a simple single parent
hierarchy? Or (2) should I use a new kind of marker that only supports a
single parent.

I'm leaning toward (2). Should this be in the core?
