HTML elements are concatenated without spaces when converting to Markdown

[shladnik]

When converting HTML containing adjacent inline elements without whitespace between them, pypandoc merges their content without adding spaces in the resulting Markdown.

before.html:
<some_tag>123</some_tag><some_tag>456</some_tag>
after.md:
123456

Sorry... that's a pandoc issue, not pypandoc.
