|What about singleton methods?

Currently, Class:Method catch *both* class method and instance method.
For other singlethon methods, object:method is available if simple
string representation is avalable, e.g.

  % ruby -r debug -e 'def self.foo; end; self.foo'
  Debug.rb
  Emacs support available.

  -e:1:def self.foo; end; self.foo
  (rdb:1) b main:foo
  Set breakpoint 1 at main:foo
  (rdb:1) c
  Breakpoint 1, foo at main:foo
  -e:1:def self.foo; end; self.foo
  (rdb:1) c
  %

With the attached patch, you can use new pattern:

  b object.method
