Incorrect whitespace handling on docs site

[Rich-Harris]

Spot the difference:

The first is the server rendered HTML — document.querySelector('ul').childNodes.length === 13. The second is after JS kicks in — document.querySelector('ul').childNodes.length === 6.

To be strictly correct, Svelte should insert whitespace between the <li> elements. It would also be acceptable if whitespace was consistently removed, perhaps with an option.

See also #189.
