Bug #2993: Module#instance_methods' flag seems to be ignored in singleton classes

ruby -v: ruby 1.9.2dev (2010-03-14 trunk 26913) [x86_64-darwin10.2.0]

Looks like the flag that tells Module#instance_methods whether to include the ones of superclasses is ignored on singleton classes. For example, in 1.9:

    class A
      def self.m
      end
    end
    p (class << A; self; end).instance_methods(false)
    # => [:m, :allocate, :new, :superclass]

    class B < A
    end
    p (class << B; self; end).instance_methods(false)
    # => [:m, :allocate, :new, :superclass]

    class C < B
    end
    p (class << C; self; end).instance_methods(false)
    # => [:m, :allocate, :new, :superclass]

I tested this against 1.9.2-head, 1.9.1, and 1.8.7, the string in the "ruby -v" form field below corresponds to the first one.
