				Subject: [PATCH] Fix whitespace when serializing empty HTML documents

				The old, non-recursive HTML serialization code would always terminate
				the output with a newline. The new implementation omitted the newline
				if the document node had no children. Readd the newline when
				serializing empty documents.

				Fixes #266.
