Fix whitespace when serializing empty HTML documents

Browse Source 
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.
