[ruby/rdoc] Allow multiple footnotes without in-between blank lines

Browse source 
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.

For now, let a footnote terminated by the next footnote mark.

Also refined the error message when undefined footnote is used.
