Preserve the blank lines typed after a list

Browse Source 
The newline to break replacement only matched paragraph to paragraph, so a blank
line after a list was dropped and the text following it glued to the last item.
Only a following paragraph is matched, because without a blank line its text
would have continued the last item instead of starting a paragraph of its own.
