https://github.com/ruby/ruby/commit/e4e054e3ce40 used four footnotes without blank lines. And the ChangeLog generated from that commit resulted in undefined method `parts' for nil error.
undefined method `parts' for nil
For now, let a footnote terminated by the next footnote mark.
Also refined the error message when undefined footnote is used.
