Subject: Add xml:space="preserve" in XML output when appropriate
With current HTML escaping, sometimes we may produce an XML tag like
<code_block> </code_block>
Many XML parsers consider these spaces insignificant and strip them
out but we need this. There's actually a test case like this in
spec.txt (search "A code block can have all empty lines as its
content:") and without proper hinting, an external xml->html converter
will fail the spec.
XML standard covers this case. If xml:space is "preserve", then
whitespaces are significant and should be kept. Add this hint for
text, code, code_block, html_inline and html_block tags.
