bug#50079: 27.2; imenu doesn't work with inline access modifier in ruby

[christopher flöß]

While editing a ruby file, invoking imenu with the following class
definition:

class Blub
  def hi
    "Hi!"
  end

  def bye
    "Bye!"
  end

  private def hiding
    "You can't see me"
  end
end

fails to list the private method `hiding`. This is valid ruby and the
method definition has a so-called inline access modifier
(`private`). With the alternative syntax (also valid ruby syntax):

class Blub
  def hi
    "Hi!"
  end

  def bye
    "Bye!"
  end

  private

  def hiding
    "You can't see me"
  end
end

imenu behaves as expected. This problem was first posted to
emacs.stackexchange.com
