- Nokogiri's pretty-printer is a bit weird. Regardless of the indentation
- setting, if an element has no child text nodes then it will be pretty-
- printed. This works by adding arbitrary whitespace to that element, and
- then all of its children are eligible to be pretty-printed.
-
- If an element has any text nodes at all, then it is not pretty-printed and
- neither are any of its descendents.
-
- Adding arbitrary whitespace to <pre> is bad, so we inject zero-width non-
- breaking spaces to prevent this. This will render fine but the spaces
- should be removed before final output to avoid problems with copy+paste.
