Ruby outline doesn’t support modifier-style method visibility

[joeldrapper]

When using modifier-style method visibility in Ruby, the outline shows the modifier as if it applies to all subsequent method definitions, even though it only applies to the one method definition.

class Example
  private def foo 
  end
  
  def bar
  end
  
  protected def baz
  end
  
  def bing
  end
  
  public def zig
  end
end

I think this is right for bare visibility modifiers.

class Example
  def foo
  end
  
  protected
  
  def bar
  end
  
  private
  
  def baz
  end
end

When the modifier applies to only one method, I think it should be part of that method’s entry in the outline

private def bar

Additionally, a non-bare visibility modifier applied to a symbol rather than a method declaration should probably be excluded from the outline entirely.

class Example
  private :foo
end

Currently, this will appear in the outline as if all subsequent methods are private, which is not correct.

This is fixed by #65 and #66 together.
